We are excited to share that the IMPRINT network was recently featured in a special edition of the Pediatric Infectious Disease Journal.

The February 2025 supplement of the journal showcases original work by participants of the 6^th International Neonatal and Maternal Immunization Symposium (INMIS) meeting held on 12-14 March 2024 in San José, Costa Rica, including several contributions by IMPRINT members. It also features an introduction to the IMPRINT network itself, highlighting IMPRINT’s efforts to establish a sustainable network that provides continuous and reliable support to research and innovation in the field of maternal and infant immunisation.
