Projects

IMPRINT network supports scientific as well as public engagement projects. Since 2017, we have been able to support a range of scientific activities which are organised around six thematic challenges representing the network’s focus areas. These activities include progression grants (PG), pump priming Projects (PP), and fellowships (FS). The public engagement projects' purpose is to facilitate imaginative, high-quality and inclusive public engagement which reaches new, global and diverse audiences. All scientific and public engagement projects which were funded by IMPRINT are listed below.

Challenge 1

Mechanism of production and transfer of maternal antibody via the placenta and breast milk

Summary
Group B streptococcus (GBS) is a bacterium commonly found in women's vaginas that can sometimes lead to severe infections in newborns. Newborns rely on antibodies transferred from their mothers through the placenta for protection against these infections.
In previous research, Shadia Khandaker and her team observed significant differences in immune responses between Bangladeshi and Malawian women. Bangladeshi women exhibited stronger immune responses, whereas Malawian women showed weaker responses. When Khandaker and her team tested serum samples from these populations on mice, they found that Bangladeshi serum provided better protection to mouse pups compared to Malawian serum. However, the reasons behind these variations remain unclear.
The project aims to investigate whether the structure of a specific type of antibody, known as Immunoglobulin G (IgG) and its interaction with placental receptors (which are like 'docking sites' where the antibody attaches during passage from the mother to the baby) contribute to these differences. Khandaker and her team will focus on sugar components of IgG called Fc N-glycan, which play a role in antibodies' function, durability and its transfer across the placenta.
By analysing these sugar components and IgG's ability to stimulate immune cells, they hope to understand why immune responses vary among populations and why antibodies are transferred differently, leading to diverse outcomes. As part of the study, a new model will be developed using cells containing human placental receptors to understand better how IgG interacts with them and which types of IgG are preferentially transferred to babies to fight GBS.
By comparing antibody properties from Bangladesh and Malawi, Khandaker and her team aim to uncover how the immune system responds differently to GBS infections in various populations. This knowledge will help identify essential criteria for better antibody function and optimal antibody transfer from motherto baby, aiding in the development of more effective and safe vaccines to protect newborns from life-threatening GBS infections.

Summary
Pregnant women sometimes carry a bacterium called Group B Streptococcus (GBS) in their vagina or rectum. During pregnancy or upon delivery, GBS may be transmitted to the baby resulting in the death of the baby in the womb or go on to cause infections such as sepsis or meningitis soon after birth. GBS disease is more serious in some low- and middle-income countries (LMICs) where pregnant women do not have access to proper antenatal care and antibiotics.
A solution would be to vaccinate mothers against GBS, so they can produce antibodies protective proteins (antibodies) that can be transferred to the baby through the placenta and protect them from developing an infection in the first place. Interestingly, LMICs situated in South-East Asia report a low GBS disease burden while high GBS disease rates are documented on the African continent, in countries such as Malawi or South Africa.
In this project Shadia Khandaker and her team aim to collect the blood of GBS-colonised mothers from high vs. low GBS disease burden countries (U.K. vs. Malawi vs. Bangladesh) and compare how the immune system of the women reacts to GBS by measuring anti-GBS antibody concentrations, the ability of the antibody to kill the bacteria, as well its ability to bind to factors present on the surface of the GBS bacteria.
They also aim to examine how effectively the antibodies are transferred across the placenta and give protection to babies.
By comparing the properties of antibodies collected from high- vs low- disease burden countries, Khandaker and her team hope to understand the criteria that are essential for the optimal transfer of GBS protective antibodies from mother to baby. Altogether this knowledge will significantly help towards the design of more efficient and safe vaccines to protect new born babies from life-threatening GBS disease.

Summary
Young infants are more susceptible to infection than individuals at any other life stage. Their immune systems are inexperienced and they are too young to benefit from infant vaccination, most of which are given several weeks after birth. In the first weeks of life, babies rely on protective proteins called antibodies, which are transferred across the placenta from the mother to the baby whilst still in the womb.
In some cases, the amount of antibody transferred to the baby is not sufficient to protect the baby from infections, such as whooping cough. Vaccines given in pregnancy aim to increase the amount of antibody in the mother’s blood, so that more antibody is transferred across the placenta to the baby so that the infant is protected until they are old enough to receive infant vaccines.
Antibody is transferred across the placenta by binding to specialised receptors on the surface of placental cells. In this project, Chrissie Jones and her team aim to study each part of the antibody-receptor interaction, namely:
• Functional changes in the antibody
• The amount and location of the antibody receptor
• The strength of the binding between the antibody and the receptor
Jones and her team aim to understand how these factors change throughout pregnancy, by testing stored blood and placental samples. They will also look at how vaccination in pregnancy can affect these factors.
In developing countries, a significant proportion of pregnant women are affected by HIV infection. This can affect how well antibody is transferred across the placenta. Jones and her team aim to understand how HIV affects the maternal antibody and how well it binds to the receptor in the placenta.
Jones her team hope that this project will help to understand more about the way babies are protected by vaccines in pregnancy and in the future, help to design vaccines that are more effective at protecting the mother and infant.

Summary
During pregnancy, the placenta is the interface between mother and baby. Its specialised structure allows nutrients and protective molecules such as antibodies to be transferred to the developing baby. These antibodies help project the infant in the first weeks of life, when the infant is exposed to viruses and bacteria for the first time.
In several countries, women are now vaccinated against certain diseases, which increases the amounts of specific antibodies passed to the baby, therefore protecting them against disease.
Surprisingly, despite the importance of trans-placental antibody transfer, there is lots that is still not known about this process. This includes how the antibody crosses all the different cell layers between the mother’s and baby’s bloodstream, how changes in the mother’s immune system may affect antibody transport, and how differences in the structure of antibodies can increase or decrease their transport to the baby.
Understanding these issues will help to optimize maternal vaccination programmes to protect infants in early life.
One way to address some of these knowledge gaps is through use of placental perfusion. This technique uses a piece of the human placenta donated after birth, which is kept in a warm chamber and bathed in fluids to copy how it functions during pregnancy. The movement of different types of antibodies across the human placenta can therefore be tracked in the laboratory, without the need for animal models. This will help to understand what regulates how well certain antibodies are passed to the baby.
This project brings together a placental biologist and an expert in antibody function, in order to answer pressing questions around how infants are protected from early-life infections, and how new vaccines can be developed in order to improve this.

Summary
Babies have more protection against some diseases (e.g. whooping cough, tetanus) in the first few months of life if their mothers are vaccinated during pregnancy. Vaccines given to mothers produce antibodies that fight disease. These ‘maternal’ antibodies are passed on to babies before birth and protect them whilst they are too young to be vaccinated themselves.
Naturally, over time, maternal antibodies in babies decline. It is therefore important that, at some point, babies receive their own vaccinations to keep them protected. Timing is important. If maternal antibodies still exist in babies when they receive their first vaccinations, they may have a lower antibody response. This may mean that they are not protected as well as they could be.
In planning vaccine programmes, therefore, it is important to understand how quickly maternal antibodies decline in babies.
Currently, there is little information about the rate at which maternal antibodies decline in babies for some common vaccines. Antibody levels may decline at different rates for different vaccines. Until there is known more, it is difficult to find out the best time to vaccinate babies.
It can be found out more by using information from studies that have already finished. Dr Voysey and her team will collect data from studies that have looked at antibody levels in two blood samples in babies. They will work out the rate at which maternal antibody levels decline in them. Combining data in this way means that there will be enough data for accurate calculations without taking any further blood samples.
This project will provide information that will help improve the planning of vaccine programmes in order to provide the best protection for babies against disease.

Challenge 2

Effects of maternal immunisation on the subsequent development of immunity in the infant

Summary
Measles remains a global health challenge, despite the availability of an effective vaccine. In areas where it's common, the World Health Organization recommends the first measles vaccine dose in infants from nine months of age. It has always been thought that infants are protected by antibodies from their mothers during the first nine months of life.
However, the number of infants under 9 months being reported with measles, raises concerns that maternal protection may have been lost before the 9-month vaccination milestone. This makes younger infants susceptible to measles and associated complications such as diarrhoea, ear and chest infections, or death.
Vaccinating infants earlier may confer protection earlier and close this window of susceptibility. However, earlier vaccination largely remains equivocal due to uncertainties on the quality and quantity of immune responses an earlier schedule might have.
This project will utilise blood samples, collected before and 28 days after the first dose of measles-rubella vaccine (MRV1) in a Ugandan clinical trial ("BoostME" study), to compare the immune responses in infants receiving MRV1 at 6 months versus infants receiving at the standard 9 months. We aim to measure and compare measles protection in the two groups using plaque reduction neutralisation titres (PRNT).
The project will also evaluate the interference maternal antibodies might have on quality and quantity of post-vaccination immune responses. If present, we will compare the magnitude and implications of such interferences.
The samples for use were collected from infants randomly allocated to three vaccination groups:
Group 1: First dose at 6 months and booster at 12 months.
Group 2: First dose at 9 months and booster at 18 months.
Group 3: First dose at 6 months and booster at 18 months.
This project will inform vaccination strategies to protect infants more effectively against measles.

Summary
Vaccinating pregnant women against pertussis is an effective tool to reduce deaths from whooping cough in their newborn infants. Pertussis antibodies are boosted in the mother and pass to infants via the placenta (or breast milk) to provide disease-specific protection. These antibodies, however, have also been shown to reduce their infant's own antibody responses when they are subsequently given routine pertussis vaccines, a phenomenon known as 'blunting'.
Previous studies show that blunting may extend to antigens not present in the maternal vaccine, but in other childhood vaccines, although the mechanisms driving this are unclear. Moreover, we do not fully understand how long functionalmaternal antibodies produced after vaccination during pregnancy persist into the postnatal period.
To investigate these important gaps in knowledge, Anja Saso and her team will test stored samples collected from up to 239 mother-infant pairs involved in the randomised control vaccine trial, GaPs (NCT03606096), recently completed by the co-applicants in The Gambia. They will rigorously characterise the antibodies produced by infants born to mothers who received the combined pertussis vaccine during pregnancy versus those who did not.
Saso and her team will focus on their responses to antigens which are not contained in the maternal pertussis vaccine, for example those in the co-administered polysaccharide-based vaccines (pneumococcal and Haemophilus influenzatype B), to address potential bystander effects. They will profile the mother's own pertussis antibodies to explore evolution in quality up to 9-months postnatally.
All proposed laboratory methods have already been developed by the co-applicants and applied successfully to a previous Thai mother-infant cohort.
The findings will help to understand the longer-term immunological impact of vaccinating pregnant women against pertussis, including in low-and-middle-income countries where data is limited, and pertussis vaccines are often not routinely given in pregnancy. This may also inform policy decisions on whether women need to be vaccinated during each pregnancy and any changes required to routine childhood immunisation schedules.

Summary
Whether vaccines given to women in pregnancy (maternal immunisation) have an effect on the developing immune system of the newborn baby are still not well understood. However, this knowledge is important to make sure that current and future vaccines used in pregnancy can be used in the most efficient and protective way.
Whilst there are better insights into the effect of the maternal vaccines on the antigen-specific, acquired immune responses in the newborn, there remains a gap in knowledge about effects of maternal vaccination on infant natural defense cells (innate immunity) and any potential modification of these cells.
This project will use cord blood samples collected within an ongoing large-scale observational study of neonatal vaccine responses to develop a prototype of assays in the lab that will allow to investigate the effects of maternal antibody on the natural defense cells in the newborn. Initially, Alansana Darboe and his team will use the model of tetanus vaccination, given that this vaccine is already routinely given to pregnant women in The Gambia.
This model can then serve to assess the potential impact of other maternal vaccines on neonatal innate responses, such as pertussis or future vaccines. In addition, Darboe and his team will examine in another lab assay whether "training" of specific cells generated from cord blood (monocytes) by BCG - another vaccine used in the newborn - can induce changes in gene expression.
They will also have the opportunity to measure if the early natural cellular responses have an influence on the antibody levels measured in response to vaccines the baby receives in the first few months of life.
This knowledge will help to estimate if there is potential for clinical impact on longer term antigen-specific immunity in the infants or not.
The fellowship is embedded in an existing strong research partnership between the three research sponsors in Gambia, Vancouver and Brussels and will provide the fellow with the opportunity to develop an independent complimentary aspect of the research around one of the key challenges identified by the IMPRINT network.

Summary
Whooping cough can cause serious disease, particularly in young infants. In the UK, and other countries around the world, it is recommended that pregnant women receive the whooping cough vaccine in order to protect mothers and infants against whooping cough. Antibodies (protective proteins) are transferred across the placenta from the mother to the infant and protect the infant in the first months of life, before the infant is protected by infant whooping cough vaccination.
There are concerns that high levels of maternal antibody in the infant at birth may prevent the infant from producing such a good response to their own vaccines.
There is a type of blood cell in the circulation called "T Follicular Helper" cells, or TFH cells for short. These cells are thought to be important for how well the body produces the protective antibody proteins in response to vaccination. It is important to understand if vaccination in pregnancy can affect how well these specialised cells develop in the infant's blood stream and therefore how well the infant responds to their own vaccines.
Other specialised cells that are important to how well the infant responds to infections like whooping cough, such as "T" cells, may also potentially be affected by vaccination in pregnancy.
In this study, Qibo Zhang and his team will work with partners in Thailand who are already carrying out studies looking at whooping cough vaccination in pregnancy. They will work with samples that have already been collected, from infants born to vaccinated mothers and infants born to unvaccinated mothers. This will allow to compare the infant's cellular response to vaccination in these different groups of infants.
The team hopes that this study will improve the understanding of infant immunity and inform future vaccination strategies.

Summary
The ultimate aim of our work is to develop vaccines that will be taken by pregnant women and which will then protect babies from catching infections caused by, for example, HIV, hepatitis B and Zika, during birth. The vaccines will be taken by mouth, but will have their effects in the mother's vagina.
The oral route of vaccine taking has been chosen as this route is expected to have higher acceptability and be cheaper than injections, which have to be sterile, need to be given by medically-trained personnel and can be painful. The cost factor is especially relevant in LMIC, for poorer people and where healthcare costs are largely borne by individuals, rather than the state.
For oral vaccines to have an influence in the vagina, they have to be prepared using specific chemicals, such that once a vaccine is swallowed, it is only processed in the large bowel (and nowhere else in the gut). In this project, Sudaxshina Murdan and her team will: i) identify those chemicals, ii) prepare the vaccines, and iii) test whether the prepared vaccines will be processed in the large bowel following swallowing.
The results of this study will be used to apply for follow-on funding to determine whether such vaccines will have an influence in the mother's vagina and protect newborns during birth.

Challenge 3

Impact of globally important co-factors on maternal and neonatal immunity

Summary
In Uganda, whooping cough affects 15-19% of children and HIV infection affects between 6-11% of pregnant women. A readily available genetically detoxified acellular pertussis-containing vaccine (Tdap) has been developed by BioNet Asia for administration to pregnant women. By vaccinating pregnant woman, infants can be protected from whooping cough in the first months of life, before they get their first wholecell pertussis (wP) vaccination.
Maternal HIV infection adversely affects infant outcomes in early life through altered immune responses, resulting in these infants being more susceptible to vaccine-preventable diseases, like whooping cough. However, whether immune responses following maternal Tdap vaccine are different in the context of maternal HIV infection has not been studied before in Uganda.
To investigate the immune responses of Tdap vaccinated vs non-vaccinated pregnant women and their infants, in the context of HIV, 181 participants (81 HIV positive and 100 HIV negative pregnant women/infant pairs) were enrolled into the WoMANPOWER study to investigate IgG responses in blood and IgA responses in breast milk. During this study, Kirsty Le Doare and her team also collected blood cells to investigate cellular responses following maternal Tdap and infant wP vaccination.
Samples were collected at 4 time points including pre- and 4 weeks post-maternal vaccination (mother), delivery (mother and cord), and 18 weeks post-delivery (infant).
This study aims to investigate immune cell subsets in pregnant women and infants, both exposed and unexposed to HIV, following maternal Tdap vaccination. Specifically, Le Doare and her team will explore whether HIV infection influences these cells' impact on antibody responses after administering the Tdap vaccine to pregnant women.
Additionally, they will assess whether antibodies can effectively prevent the whooping cough bacterium from adhering to the nose and throat, which is the primary cause of symptoms during the disease.

Summary
During pregnancy, maternal immune memory is transferred via the placenta to the fetus as antibodies - highly specific proteins that provide defence against invading pathogens. Transplacental antibody transfer confers a degree of protection to the neonate upon microbial exposure following birth. Maternal immunisation boosts pathogen-specific antibodies during pregnancy benefiting the mother and the neonate.
In previous work in animals and young children, Andrew Armitage and his team have found that iron deficiency anaemia can inhibit responses to vaccines, and that iron can improve responses.
In this project, Armitage and his team want to assess how maternal iron status, iron supplements, inflammation, and other factors, affect efficiency of transplacental antibody transfer. Their ongoing clinical trial – named IRONMUM – is recruiting women with or without anaemia from the Myanmar-border area of Thailand: participants receive Diphtheria-Tetanus and COVID vaccinations together with iron-containing micronutrient supplements according to their anaemia status.
The main IRONMUM outcome is the effect of iron on the initial immune response to vaccination and improvement of anaemia. Here, Armitage and his team will extend the work by measuring antibody concentrations – both those induced by maternal vaccination and other antibodies specific to previous exposures (e.g. measles) – in maternal samples from late in pregnancy and in umbilical cord blood from the neonate.
Inflammation can also influence the placenta: they will additionally characterise hundreds of mediators of inflammation. The team will calculate transplacental antibody transfer and relate this to iron and inflammatory status of the mother at vaccination and in late pregnancy. They will also assess types of sugars present on the antibodies, since these may influence transfer efficiency.
Together, the data will identify key factors influencing the effectiveness of transplacental antibody transfer, especially following maternal immunisation in women in whom iron deficiency, anaemia and inflammation are all common. This will help inform future strategies aimed at maximising the benefit of maternal immunisation for both mothers and neonates.

Summary
Infections and nutritional deficiencies, including iron deficiency, affect millions of young children in low- and middle-income countries (LMICs). Moreover, iron deficiency has recently been reported as the most common cause of preventable death and disability in such settings. Recent evidence indicates that iron is essential for effective immune responses, so iron deficiency could therefore contribute to impaired immunity leading to poor responses to vaccines and infection susceptibility in infants.
However, the ways in which iron deficiency, and treating infants with iron supplements, influence infant immunity in LMIC settings remains poorly explored.
This project will address this issue by applying a state-of-the-art immunological method termed CyTOF to blood samples obtained from infants participating in a large clinical trial of iron supplementation in Bangladesh; this trial is investigating the relative pros and cons of iron treatments for infants. CyTOF will enable Andrew Armitage and his team to study how iron affects the array of different types of white blood cells in circulation, and the functioning of these different immune cell types.
This information will be linked with data collected concurrently from the same infants including their immune responses to the measles-rubella vaccine, the diversity of microorganisms found in their intestine, as well as data on infection, growth and developmental.
Together, the study will advance understanding of how nutrition can shape development of the immune system in infants in settings were the ability to mount competent immune responses to immunisations and infections is of great importance. The data will also inform global health policy makers in developing guidelines regarding the use of iron treatments in infants in infection-susceptible populations.

Summary
Globally each year more than 1 million infants die from infections, and most of these deaths occur in low-income countries. The time that children are at highest risk of serious infections is during the first few months after birth.
A large study conducted in India found that supplementing newborns during the first 10 days of life with probiotics, which are live, harmless bacteria, lowered the risk for sepsis, diarrhoea and lower respiratory tract infections. The beneficial effect of probiotics on preventing respiratory tract infections in particular was unexpected and intriguing, suggesting that the effect of probiotics goes beyond that of a healthy gut.
Infants in Papua New Guinea (PNG) have one of the highest risk in the world for severe respiratory infections caused by Streptococcus pneumoniae (pneumococcus), including pneumonia. Before the pneumococcus causes disease, it first colonises the infant's nose. In PNG, almost all infants have been colonized with pneumococci by the age of 1 month.
The aim of this project is to conduct a pilot study to test two probiotic supplementations for safety and possible effects on early pneumococcal colonization and pneumococcal vaccine responses in PNG infants. This pilot study will support the implementation of a subsequent large clinical trial that will aim to study in PNG infants the direct and indirect impacts (by improving vaccine responses) of probiotics on serious infections including severe pneumonia, blood poisoning and meningitis.
If proven to be efficient, probiotics supplementation could be a simple, safe and affordable intervention to safe infants' lives.

Summary
Oral vaccines are less effective in low-income than high-income countries, significantly limiting their potential public health impact. Despite considerable effort, the mechanisms responsible for this phenomenon remain elusive. However, there is good reason to suspect that intestinal viruses may be important. Indeed, these viruses have consistently been shown to interfere with the oral poliovirus vaccine and might also affect other vaccines given by mouth.
Recent developments in genetic sequencing techniques have enabled us to examine intestinal viruses with more precision than ever before. Rather than testing for viruses one by one, we can now detect many different families of viruses simultaneously. These 'deep sequencing' methods are likely to offer valuable insight into the impact of early-life viral exposure on immune development and vaccine response.
Edward Parker and his team plan to use deep sequencing to measure the composition of intestinal viruses among infants in the UK and Malawi, who recently took part in a study of oral rotavirus vaccine.
By measuring viral exposure at multiple times in the first 4 months of life, they will determine whether infants in the two cohorts are exposed to different viruses (a question that has not previously been explored using deep sequencing) and also whether viral exposure is greater among Malawian infants that failed to respond to the rotavirus vaccine.
The virome remains one of the unexplored frontiers of our microbiome. This study will help to establish the impact of the virome on oral vaccine response in early life, potentially helping to identify interventions that will improve vaccine effectiveness.

Challenge 4

Vaccine acceptancy and preparedness for maternal immunisation, including in emergencies

Summary
Vaccination during pregnancy, also known as maternal immunisation, has the potential to prevent disease and death among mothers and their infants. Maternal immunisation can have tremendous impact in low and middle-income countries (LMICs) where burden of disease is very high and access to adequate healthcare can be problematic. However, not everyone is willing to accept vaccines, especially during pregnancy, due to safety and other concerns.
Available maternal vaccines are safe and effective in preventing disease. Not taking vaccines puts the women and their children at risk of what can often be severe disease and this poses a significant public health challenge that needs to be addressed.
This research project aims to identify factors of practical value that may affect individual vaccine acceptance during pregnancy. Neisha Sundaram and her team will consider individual concerns and priorities, and factors beyond individual decision-making. This would include the influence of healthcare provider recommendation, facilitators and barriers to healthcare provider recommendation and the influence of policies and policy-maker priorities on vaccine acceptance.
They also seek to understand the influence of contextual social, cultural, historical, political, economic, religious and media-related factors on vaccine acceptance.
Sundaram and her team think that it is important to take a broad approach. Focusing on individual factors alone without considering wider influences of provider-level, policy/programme-level and contextual factors on vaccine acceptance is akin to studying diet and nutrition as determined purely by individual choice without consideration of social, cultural or financial circumstances.
Sundaram and her team will conduct this research in India using a number of methods, including in-depth interviews, focus groups discussions and document review. Research participants will include pregnant women and new mothers, public and private healthcare providers, and policy-makers and key stakeholders.
As a study outcome they will develop a comprehensive framework that looks at the relationship between public, provider, policy, structural and contextual factors on individual vaccine acceptance in order to identify ways to maximise access to and acceptance of safe and effective maternal vaccines.

Summary
Giving vaccines to pregnant women is a useful public health measure. It will help to reduce death and disease among pregnant women and newborn infants from infectious diseases. This will be most important in low- and middle-income countries (LMICs). New vaccines are being developed for use in pregnant women, e.g., for Group B streptococcus, Respiratory Syncytial virus and cytomegalovirus.
The safety of vaccines administered to pregnant women is most important for pregnant women, healthcare providers, researchers, regulators, ethics committees, vaccine developers and communities. There is a need for a globally coordinated approach to determine the safety of vaccines used for pregnant women and for Maternal and Child Health (MCH) studies.
The GAIA (Global Alignment of Immunization safety Assessment in pregnancy) project has developed 21 globally consistent tools (case definitions of key terms) to determine the safety of vaccines in pregnancy. These can also be used for MCH studies. Assessment of these tools in LMICs is required. This study will assess key case definitions and terms using data from clinical studies conducted in South Africa and The Gambia.
The study will determine how possible it is to utilize the case definitions, the quality and accuracy of the data collected, the challenges and advantages of using the case definitions and collection of any possible edits to the case definitions that would make them easy to use in LMICs.

Summary
Vaccines have prevented millions of child deaths; however, 45% of remaining under-5 deaths occur during the neonatal period, when infants are vulnerable to disease. Immunisation of pregnant women with tetanus toxoid to protect mother and newborn from tetanus has been widely implemented and accepted.
Maternal immunisation has the potential to reduce or prevent stillbirths and neonatal deaths from other diseases including influenza, pertussis, Group B streptococcus and Respiratory Syncytial virus. Pregnant women have not been included in clinical trials for most vaccines and medicines, due to concerns about potentially detrimental side effects on foetus/ infant and mother.
It is important to understand knowledge, perceptions and acceptance of maternal immunisation programs in different countries, especially low- middle income countries, where the vast majority of stillbirths, neonatal infections and deaths occur. Additionally, understanding of the suitability of and resources available at local health care facilities to implement large-scale maternal immunisation programs is important to enable smooth and effective roll-out of maternal immunisation programs.
South African sites have been involved in vaccine-preventable disease (VPD) surveillance programs and maternal immunisation trials, and the large burden of VPD in new-borns encourages rapid roll-out of MI programs.
In this study, Clare Cutland and her team aim to first describe the perceptions about and acceptability of maternal immunisation amongst communities in urban (Soweto, Johannesburg, Gauteng) and rural (Somkhele, Mtubatuba, KwaZulu-Natal) communities in South Africa; second to understand the social and cultural factors which impact on the acceptability of maternal immunisation; and third to assess health care worker and facility preparedness for roll-out of MI programs.
In order to fulfill these outcomes, they will conduct interviews and group discussions with community members, and an electronic survey of health care workers.

Challenge 5

Vaccine safety monitoring in LMIC

Summary
The InVxSIM project will set up a vaccine safety monitoring system in rural Uganda within the Iganga Mayuge health and demographic surveillance system (HDSS). It will focus on maternal and neonatal vaccine acceptability and safety. This project will be implemented in a population of over 90,000 individuals of which 18% are women in reproductive age.
The HDSS demographic updates data that we routinely collect will be linked to the health facility electronic health records system which captures antenatal care for the mother and vaccinations in mothers and children.
The InVxSIM project will first assess the ability to measure obstetric and neonatal outcomes as defined in the GAIA project. It will also monitor the safety of maternal immunization to ensure that potential concerns are addressed rapidly. Lastly, Dan Kajungu and his team will build a system for identification, follow-up and delivery of reminders to get immunized to pregnant women.
They hope that the project will improve information on vaccine safety, uptake and coverage, and thereby facilitate to maintain and improve trust in the maternal and neonatal immunization programs by being able to provide requested information rapidly. This may ultimately reduce mortality and morbidity because of better prevention of vaccine preventable diseases and be an example for other low- and middle-income countries (LMICs) that may have similar fragmented information systems.

Challenge 6

Development of comparable methodologies for assessing efficacy in clinical trials

Summary
In areas with limited resources where pregnancy issues are frequent, selecting the right participants for maternal immunization studies can be challenging. While eligibility criteria are crucial for ensuring participant safety and obtaining reliable results, overly strict rules may exclude a large part of the population, limiting the generalizability of the findings. Maternal vaccine research usually prioritizes low-risk participants to reduce the risk of adverse effects.
The aim of this project is to create an eligibility assessment tool that can be used for maternal immunisation clinical trials in low resource settings.
Objectives:
To investigate how many women are excluded from maternal vaccine research in Kampala, Uganda based on trial criteria from recent maternal vaccine trials.
To identify pregnancy outcomes of expectant mothers who would not have been selected for vaccine research based on eligibility criteria from recent maternal vaccine trials.
To assess how well current eligibility criteria can forecast a low-risk pregnancy.
The research will create a tool to select participants by merging existing recruitment criteria used to select pregnant women for two maternal vaccine studies. The plan is to use this selection tool on women who took part in a previous study (PREPARE WP2) that gathered data on pregnancy, neonatal, and infant outcomes at Kawempe National Referral Hospital in Kampala, Uganda at the same time as the two maternal vaccine studies were taking place.
This study will offer insightful information to guide future research on maternal vaccines, improving eligibility requirements to permit more people to participate, which could improve the trial's inclusiveness, generalizability, and relevance.

Summary
Tuberculosis (TB) is a disease caused by a germ that can affect the lungs and in severe cases, the blood and the brain. Almost one million children, mostly from the tropics, suffered from TB in the year 2015. A vaccine called BCG is used to prevent this disease. It is given to babies and is able to prevent severe forms of TB that involve the blood and the brain, but does not provide adequate protection from the lung form, which is the most common.
New vaccines that are able to do a better job at preventing TB in babies are needed. VPM1002 is a vaccine that has been developed to work better than BCG. It has been tested in adults and babies and the results show that it is safe, however there is a need to know how well it is able to kill TB germs. This study aims to use a tool in the lab to show how well the new vaccine, VPM1002 works in babies from Uganda, an African country where TB is common.

Public Engagement Projects

Summary
Although the Expanded Programme on Immunization in Vietnam has reported high rates for vaccine uptake (> 90% for most childhood and maternal vaccines), these figures mask massive differences across the country. Recent outbreaks of vaccine preventable diseases (VPDs) also highlight pockets of communities with very low uptake. Most of these communities are remote and ethnic minority groups.
The project team's previous research with ethnic minority communities in the mountainous central region of Vietnam revealed the pivotal role of the village health workers in supporting mothers to access vaccination for themselves and their children. It also uncovered both a general willingness to accept vaccines, but also significant misconceptions and fears prevalent among rural communities.
The findings highlight critical knowledge gaps and barriers to vaccination faced by both communities and healthcare workers. According to the World Health Organization, effective community engagement is essential for improving vaccination coverage and overcoming barriers to immunisation.
In this project, Yen Nguyen and team address these challenges through co-created engagement methods such as short films, community screenings and village health talks. These approaches aim to foster constructive dialogue between healthcare workers and communities, enhancing understanding and acceptance of vaccines, ultimately helping to provide children with the healthy lives they deserve.
The project team will collaborate with longstanding health service partners in Dak Lak Province to implement targeted community engagement activities. Building on insights from team member Ha Nguyen's research, the team will collaborate with local health providers and community members to develop and disseminate tailored public health messages.
The focus of the project is on rural, ethnic minority communities in Dak Lak Province, selected due to their historically low vaccine uptake rates and vulnerability to outbreaks of vaccine-preventable diseases. This project represents a critical step toward ensuring equitable healthcare access and disease prevention for Dak Lak's vulnerable populations.

Summary
As the disease landscape changes, methods of disease prevention need to change as well. New vaccines are being developed for vaccine-preventable diseases, as well as new schedules for already existing vaccine delivery. Before a country can take on these new vaccines or schedules, local context data is needed, that is best generated by rigorous local vaccine trials.
Although several maternal and infant vaccine trials are being carried out in Uganda, a major barrier to recruitment and retention is refusal of participation by male partners of pregnant women or fathers of children recruited to the studies, because of low engagement with these at the point of recruitment.
This project aims to increase community engagement with male partners of women of childbearing age, to improve awareness and understanding of maternal and infant vaccine trials, build confidence and address risk perceptions.
The first approach will be reaching out to men in the communities to discuss knowledge gaps and concerns about maternal and infant vaccine trials.
With this information, Mary Kyohere and her team will develop films, leaflets and other material together with peer fathers (men whose partners or children have been involved in a vaccine trial), community influencers and study team members, to create awareness and understanding of maternal and infant vaccine trials.
Kyohere and her team will work with male community influencers and village health teams to create awareness, organise and mobilise men for community events. During the community events, films will be shown, and peer fathers, influencers and study team members will engage with the men about maternal and infant vaccine trials.
To evaluate the project impact, Kyohere and her team will conduct baseline and endline surveys, and continuous monitoring to assess increased awareness and acceptability of the methods used. Rates of recruitment and retention in the ongoing maternal and infant vaccine trials will be reviewed to assess change.

Summary
In Malaysian culture, extended family members significantly influence women's maternal health choices, including vaccination. Studies have found vaccine hesitancy rates as high as 12% in Malaysia. This public engagement project aims to promote maternal vaccination in Malaysia using a mixed-method approach comprising TikTok videos, expert talks, and training vaccination champions to enhance knowledge, attitudes, and acceptance in a culturally appropriate manner.
The project will be executed through six work packages (WPs):
Identify factors influencing maternal vaccination uptake through focus group discussions with pregnant women.
Explore healthcare workers' perspectives on maternal vaccines via surveys.
Create short TikTok videos addressing concerns identified in WP1 and WP2.
Train healthcare students to become vaccination champions, promoting vaccination in their communities.
Use TikTok videos and expert talks to engage the public and disseminate the importance of maternal vaccination.
Evaluate the project's impact by assessing knowledge, attitudes, and uptake rates before and after the project.
WP1 and WP2 will reveal major concerns and actual scenarios regarding vaccination barriers, guiding TikTok video creation. In WP3, TikTok,as a major recreational platform, is expected to best engage people for maximum reach. WP4 will not only train healthcare workers for this project but also prepare them for future challenges in their careers, especially in educating the public about health issues. WP5 employs both one-way and two-way communication methods for better understanding.
WP6 will evaluate the project's effectiveness,serving as a reference for future activities. The project team anticipates increased knowledge and attitude changes as immediate effects, followed by increased inquiries about maternal vaccination and higher vaccination rates as medium-term impacts. The long-term impact would be improved delivery outcomes against vaccine-preventable diseases.

Summary
Perinatal infections remain a major cause of maternal and neonatal morbidity and mortality in Nepal.
According to the latest national demographic health survey, Nepal has a maternal mortality ratio (MMR) of 151 per 100,000 live births, a neonatal mortality ratio (NMR) of 21 deaths per 1,000 live births, and reported 2,186 perinatal deaths annually (macerated stillbirths: 53.9%, fresh still births: 19.6%, and early neonatal deaths: 26.5%), with infection being one of the top causes of maternal-perinatal mortality.
Global evidence suggests that maternal immunisation against common bacterial and viral infections that cause different diseases (e.g.,diphtheria, tetanus, pertussis, influenza, COVID-19, RSV) greatly benefits mothers and their newborn babies. Despite this, there is general hesitancy and perceived health risks associated with vaccination among pregnant women, health service providers and public in general, especially for newer vaccines.
This project aims to develop a short documentary to address awareness gaps in maternal vaccination in Nepal and explore the reasons behind vaccine hesitancy and address safety concerns. To set the scene, Suraj Bhattarai and his team will first organize a round-table workshop with clinicians, immunisation experts and an audio-visual team and then co-develop a script for a short documentary.
They will interview key stakeholders at the Ministry of Health and Population, from the WHO Programme for Vaccine-Preventable Diseases and Immunization, clinicians, nurses, vaccination officers and pregnant women. They will also collaborate with female social media influencers (celebrities) and social activists.
The project team will host a conclusive consultative meeting in Kathmandu with local key stakeholders to review the draft documentary and refine it based on the stakeholders' feedback. After confirming that the project output satisfies all authorities, the project team will publish the documentary through national television, various social media and other online platforms, and monitor the altimetric of public engagement on all the platforms.

Summary
In Tanzania, maternal vaccination remains a critical yet often overlooked aspect of public health. Maternal vaccination plays a pivotal role in reducing maternal and neonatal mortality rates by preventing diseases such as tetanus, influenza, and pertussis during pregnancy. Despite the availability of vaccines, awareness and uptake remain suboptimal in many regions of Tanzania.
With this in mind, finding unique ways to promote maternal vaccination through digital media is the strategy that this project will employ.
Research in 2021 in Tanzania revealed that 51% of participants perceive community radio stations as improving access to information, including news, current affairs, and educational content. It also highlighted how radio stations contribute to increased information dissemination, covering news, current affairs, and educational topics.
The project aims to empower journalists and media personalities to become advocates for maternal vaccination awareness through targeted training and collaboration with healthcare professionals. Empowering journalists is crucial as they are key influencers who can effectively disseminate accurate information, debunk myths, and educate communities through the media platform.
By equipping journalists with knowledge about maternal vaccination, they can amplify its importance and encourage community engagement and uptake. This project's activities will include selecting journalists and radio/media personalities across Tanzania to participate in a maternal vaccination awareness-raising workshop. Firstly, healthcare professionals will conduct workshops for journalists focusing on understanding vaccine importance,and benefits, and addressing misconceptions.
Secondly, journalists will collaborate on media campaigns highlighting vaccination benefits across radio and social media, airing broadcast messages with midwives.
By empowering journalists and media personalities through targeted training and collaboration with healthcare professionals, the project aims to foster a supportive environment where accurate information on maternal vaccination is readily available and widely disseminated. This initiative not only seeks to improve awareness but also to increase maternal vaccination rates in Tanzania.

Summary
Vaccination is highly effective in preventing infectious diseases, but vaccination rates remain low in many rural areas of developing countries like Nigeria. This is due to logistical, economic, cultural, and informational barriers. To overcome these challenges, innovative strategies that align with local cultural contexts are needed. Therefore, culturally relevant health messages communicated in native languages are essential for improving vaccination acceptance and uptake.
This project will use culturally adapted audio messaging,specifically local music, to promote maternal and infant vaccination in rural Southeast Nigeria. Music, a vital part of Nigerian culture, offers a familiar and engaging way to convey health messages. Historically, music has educated,entertained, and united communities, making it an effective tool for spreading vaccination information.
By translating vaccination information into local languages and incorporating it into traditional music, the project aims to improve understanding and acceptance of vaccination, promote community engagement, address misconceptions around vaccination, build trust, and encourage positive health behaviours among mothers and caregivers.
The project is guided by the Health Belief Model (HBM) andthe Diffusion of Innovations (DOI) theory. The HBM explains how individual beliefs about health risks and benefits influence vaccination decisions. The DOI theory provides insights into how the new audio messaging strategy is adopted within the community.
The significance of this project lies in its potential to offer an evidence-based strategy for improving vaccination outreach in culturally diverse settings. It seeks to bridge the gap between modern healthcare practices and local cultural norms. The findings are expected to inform public health policies and interventions.
In conclusion, this project aims to show that culturally tailored audio messaging, rooted in local musical traditions, can significantly promote maternal and infant vaccinations in rural Nigeria. Through this approach, the project hopes to contribute to the broader goal of achieving equitable healthcare access and improving public health in culturally diverse populations.

Summary
These activities led by Queen Mary University of London in partnership with Teesside University use historical materials related to infection during pregnancy and maternal vaccination to engage with the public in East London and North-East England.
The collaboration between historians and healthcare professionals aims to use the past as a springboard for contemporary conversations with community groups in Tower Hamlets and the Tees Valley – two areas noted for healthcare disparities and challenges with vaccine uptake.
Presenting these historical materials at a baby fair, summer science festivals, and school outreach workshops, the project aims to:
Place maternal immunisation within a longer historical tradition and unpack narratives around risk.
Create a safe space for conversations about maternal vaccination, addressing myths and misinformation.
Use historical public health materials to examine contemporary messages and inform future communication strategies.
This initiative seeks to foster a better understanding and uptake of maternal immunisation by connecting historical insights with modern healthcare practices, encouraging informed and meaningful discussions.

Summary
This project aims to establish a pool of school-going adolescent girls and boys as 'immunisation ambassadors' and change agents able to engage and empower mothers and community members and link them to maternal and neonatal immunisation services.
One way of linking mothers and communities to immunisation services is by educating their daughters and sons as 'immunisation ambassadors' and mediators between their mothers and immunisation services. Up to 400 girls and 100 boys aged 15-19 years from 10 rural secondary schools in Entebbe, Uganda, will be asked to participate in this project. They will be trained on vaccines, on the importance of timely vaccination and maternal immunisation, and on leadership skills.
This will equip them to become 'immunisation ambassadors' and community leaders, who will link their mothers and communities to maternal and neonatal immunisation services.
This project will reduce maternal and neonatal morbidity and mortality, and will contribute to achieving the Sustainable Development Goal target of ending preventable deaths of newborns and children under five years of age by 2030.

Summary
This aim of this project is to increase awareness of maternal immunisation in the ten parishes surrounding a maternal health specialty, Kawempe National Referral Hospital, in Uganda. The primary target audience are pregnant women and women of child-bearing age and their influencers. The focus will be on community education emphasizing the benefits and dispelling myths and misconceptions of maternal vaccines; using these to trace and refer women who default on the maternal immunisation schedule.
Using mixed methods of health promotion, the project will leverage various media channels including mobile films at community level, radio messaging, and women influencers' support groups.
The first approach is to create folk media content by utilising a mix of cite5†video†www.youtube.com , audio and art to create awareness of maternal vaccination at community level. The media content will be developed together with pregnant women (peers), older women and men who are exemplary in the community in supporting primary health programmes.
The second strategy is to use women influencers to create awareness at household level, trace and refer eligible cases for immunisation and babies with neonatal infections for treatment. The influencers will undergo training using the Ministry of Health village health team curriculum with additional content customised to the project.
The third strategy is to develop and disseminate tailored radio spot messages and infographics on vaccination to create positive perceptions of immunisation. Mary Kyohere and her team will work with the district health teams to engage with communities in live information and question sessions on maternal immunisation in local radio programmes.

Summary
This project aims to increase the knowledge and promote change in social norms and behaviour pertaining to vaccination during pregnancy and the neonatal period among tribal communities in India. It will give emphasis to establishing a system within the communities, which resolves challenges and barriers related to antenatal and postnatal care, institutional delivery, neonatal health, and early immunisation.
It includes the support of discussions on maternal and child-related issues in various local forums such as traditional village assemblies, Village Health Sanitation and Nutrition Days, and planning meetings of the local government. The project will also focus on capacity building and strengthening the healthcare system by promoting community-based actions with a sustainable model of community media action led by tribal people.
This model comprises the use of community radio, podcasts, and other cite6†media†www.youtube.com produced by tribal people, primarily women, to propagate their views and experiences in maternal and child health including vaccination. Thus, health communication will be done by the community members themselves, especially the women, which contributes to an enhanced comprehensibility and a strong commitment and ownership of the tribal people.
The active facilitation of the dialogue between the tribal population and service providers will help break down barriers existing for many years and strengthen community capacities towards sustainable developments in the area of maternal immunisation.

Summary
Tetanus toxoid (TT) vaccine provided during antenatal clinic visits has proven to protect newborns from neonatal tetanus, which has a mortality rate between 30% and 70% in developing countries. The recommended dosage of TT is 5 doses; but due to a lack of awareness of TT vaccination in the communities and among women of child-bearing age, most women in Tanzania receive only 1 TT shot. Factors contributing to the receipt of two or more TT doses are higher education, wealth, and urban residence.
Aspects reducing the probability of receiving the recommended dosage include a lack of awareness and misconceptions about the vaccination, specific socio-cultural beliefs, a long distance between residence and health facilities as well as different barriers related to the health system.
This project aims to strengthen maternal vaccination awareness among communities in remote areas of the Kilimanjaro region, which will in turn improve the uptake of maternal vaccines in the future. It includes three phases:
Phase one is to educate and sensitise healthcare workers (nurse-midwives) in the importance of maternal vaccination.
Phase two is to educate community leaders to enhance one-on-one promotion of the importance of maternal vaccination with the assistance of midwives from phase one.
Phase three is to educate communities during their local meeting sessions with trained midwives and community leaders from phase one and two.
The project is expected to have a positive impact on maternal vaccination awareness, especially in remote areas, and will act as a precursor for sustainable programmes in other remote areas of the country.

Summary
The goal of this project is to address risk perceptions around maternal vaccination that contribute to vaccine hesitancy in Kilifi, a rural coastal area, and in Kibera, an informal settlement, in Nairobi.
To achieve this goal, Patience Kerubo Kiyuka and her team will use magnet theatre – a form of community theatre that takes place in public spaces. Magnet theatre allows community members to participate in the dialogue and thus offers them an opportunity to reflect on the issues being addressed. A baseline evaluation of the awareness and risk perception on maternal vaccination will be carried out in women of reproductive age (15-45 years) using questionnaires and focus group discussions.
The script for the magnet theatre will be written to convey the health benefits of maternal vaccination while addressing the risk perceptions. Additionally, podcasts will be produced that will be posted online to reach a wider audience.
For ownership and sustainability purposes, the Ministry of Health (MoH) will be a crucial partner in this project. Kiyuka and her team will work closely with them to develop the play. At the end of the study, the recorded play will be shared with the MoH so that it can be used by them during community health outreach events. By addressing barriers to maternal immunisation, the project aims to contribute to increased vaccination rates and ultimately help reduce vaccine-preventable neonatal mortality.

Summary
Traditional birth attendants (TBAs) are community based, informally trained providers of maternal care during pregnancy, childbirth and after delivery; and they form an integral part of the social, cultural and religious fabric in most communities in Nigeria. Therefore, TBAs have the potential to contribute significantly to the uptake of maternal and neonatal immunisation.
Despite their limitations in handling the complications of childbirth and the Government's promotion of hospital based skilled birth attendants as the safer option, the TBAs are widely accepted and patronized, especially in resource limited environments. The aim of the project will be to engage and empower the TBAs to be more knowledgeable with positive attitude in order to develop the willingness to promote uptake of maternal and neonatal immunisation.
Ninety TBA participants will be selected from proximal rural areas within each of the three senatorial geopolitical zones of Imo State in Nigeria. The TBAs will be engaged and linked to Health Facility Immunisation Focal Persons through an audio-visually structured workshop that will take into cognizance their level of education, customs and traditions.
A pre- and post-training interviewer administered questionnaire will be used to evaluate the program with respect to the level of knowledge, attitude and willingness to promote immunisation.

Summary
Games can provide a format for reaching a large audience to disseminate important educational messages in a fun and readily available manner. Therefore, Hal Drakesmith and his team aim to develop a cite7†game†mrcwimm.itch.io that allows the user to 'design' a vaccine and understand how a vaccine can protect populations against spreading infections.
The goal is the full development and beta testing of the game, and its release via conduits available to the team through well-established public engagement activities in Oxford, the UK, as well as in LMICs (e.g. MRC Gambia, KEMRI, icddr,b). The target group includes science teachers, sixth-form students, women thinking about pregnancy, researchers running vaccine trials (who may need to help educate intended vaccinees), and organizations who promote vaccination.
After release, Drakesmith and his team will evaluate the impact of the game via monitoring numbers of downloads, collecting generic information about the player population, and asking the players themselves to describe their views on vaccination before and after playing.

Summary
Role play as an information, education and communication (IEC) tool can influence people's choices and behaviors. This project is aimed at creating awareness of the risks associated with non-immunisation and to stir up the women's risk perception and improve uptake of maternal vaccination with Tetanus toxoid (TT). This will be a quasi-experimental study with a before and after design among women in the reproductive age group (15-49 years) in rural communities in Ebonyi State, Nigeria.
A multi-staged sampling technique will be used to select 600 participants.
The study will employ short-films and role plays performed by role model actors in the communities during their public events. Pamphlets will also be designed and distributed in the local language. A baseline evaluation of knowledge, risk perception and trust in maternal vaccination among the respondents will be carried out using questionnaire pre- and post-intervention and focus group discussions prior to the commencement of the intervention.
The role play and film scripts will be written to convey the health benefits of tetanus toxoid and Hepatitis B vaccinations and negative effects of the disease.
The proportion of women who are aware, have good knowledge, good perception of and are able to take up maternal vaccinations will be compared before and after the intervention.

Summary
This project aims to capture and share perceptions of maternal and neonatal vaccination in three nations – the UK, Malawi and Bangladesh – which contrast in their socio-economical status, immunisation policies, ready access to antenatal health care resources and vaccine confidence levels. Using consultation groups and semi-structured interviews, Marie Yang and her team aim to produce a short-film portraying multi-national perceptions of maternal and neonatal immunisation.
This short-film will then be presented to communities and audiences located within these same three locations. Yang and her team will evaluate the impact of the short-film viewing and shared experiences on vaccine confidence and/or changes in perspectives around vaccination. Written feedback from participants will also be used to inform future funding initiatives, and disseminate similar short-films.
The project is timely in that it builds upon an existing platform of collaborating researchers based in three different countries and has the ultimate goal of promoting communication about vaccination with parents and communities living in low- and middle-income countries (LMICs).

Summary
This project seeks to raise awareness on available maternal vaccines like tetanus in existing government health facilities of Mukono and Wakiso districts in Uganda through mass media communication by use of existing local FM radio stations. The focus is on fishing communities as they have limited access to health facilities.
Brenda Okech and her team seek to build the capacity of 50 Community Health Extension Workers (CHEWs) on the available maternal vaccines. This will include knowledge of advantages, disadvantages of maternal vaccination as well as mobilization and counseling skills. Capacity will also be built in recording, reporting vaccinations and health unit referral systems to ensure improved access, providing ongoing education and support services for the mothers.
Okech and her team also hope to strengthen awareness on maternal vaccination by integrating it with antenatal care, maternal and child health services among 400 expectant mothers and children through antenatal outreach at health facilities.
The team furthermore aims to build the capacity of 50 secondary students to develop skits on maternal vaccines to be presented at fishing communities and/or the Uganda Virus Research Institute (UVRI).
Community education sessions on maternal vaccines will be conducted and student drama groups will be engaged and trained on maternal vaccine information. They will be supported to conduct drama shows. Local radio stations will also be engaged to support the cause.
To realize the above objectives, these activities will be implemented in collaboration with the government health facilities with UVRI-IAVI being the lead agency.
