IntroductionThe Americas committed to strengthening maternal and neonatal immunization (MNI) through the Pan American Health Organization (PAHO) Regional Immunization Action Plan (RIAP) 2016-20. We describe the progress toward RIAP MNI-related targets and those related to improvement of data quality and information systems; analyze national MNI policies and vaccination coverages; and identify enablers and challenges of monitoring and reporting MNI vaccination coverage in Latin America and the Caribbean (LAC).MethodologyDescriptive study of national MNI policies, vaccination coverage, and information systems. Sources of information included PAHO-World Health Organization (WHO) / UNICEF Joint Reporting Forms on immunization (JRF) 2013-2019, and other reports.ResultsLAC has met two of three RIAP targets related to MNI (countries with universal hepatitis B birth dose introduction and elimination of maternal and neonatal tetanus) and is on track to meet the other (countries with vaccination of pregnant women). As of 2018, of the 49 countries and territories in LAC, 32 vaccinate pregnant women against influenza and 29 provide tetanus-containing vaccine. Twenty-five countries offer universal hepatitis B birth dose vaccine and 31 offer BCG vaccine. In 2018, regional influenza vaccine coverage among pregnant woman was 75%. Regional coverages for BCG and hepatitis B birth dose (<24 h) vaccines were 93% and 79%, respectively. Countries have exceeded RIAP targets related to the quality of vaccination coverage data and the establishment of electronic immunization registries (EIRs). Challenges in monitoring MNI coverage include estimation of denominators and difficulties disaggregating data by group (e.g., pregnant women versus other groups).ConclusionDespite progress in improving MNI in LAC, countries must further strengthen immunization monitoring systems and data quality to better report vaccination coverage among pregnant women and newborns. EIR and MNI information systems must be integrated, such that countries can use accurate data to design more timely and effective vaccination strategies.Copyright © 2020 The Authors.
