The International Maternal Newborn Health Conference (IMNHC) series is organized by the AlignMNH Secretariat and the maternal newborn health community, and it is designed to create an opportunity to bring forward new evidence, create an opportunity for conversation, and bring together maternal newborn health efforts. The conference series will be held every two years to maintain our global progress towards improving maternal newborn health with the first convening, IMNHC 2023, in Cape Town, South Africa from May 8-11, 2023.
