Gathering information on maternal immunization readiness in Bangladesh, Ghana, Kenya, Mozambique, and Nepal: Applying a WHO checklist.

New respiratory syncytial virus (RSV) maternal vaccines have begun roll out in some countries, with efforts in progress to broaden access worldwide and shorten the timeline to access for low- and middle-income countries (LMICs). Prior to new maternal immunization (MI) introductions, countries will need to evaluate their capacity and readiness for successful introduction. The World Health Organization's Maternal Immunization and Antenatal Care Situation Analysis (MIACSA) project (2016-2019) developed a checklist for countries to self-evaluate their capacity to introduce new maternal vaccines. Here, we report on our use of the MIACSA checklist in Bangladesh, Ghana, Kenya, Mozambique, and Nepal to gather country stakeholders' perceptions of MI readiness and provide additional considerations for implementers when using the checklist to optimize its usefulness.
