This manual provides guidance for countries on monitoring and reporting vaccination coverage for seasonal influenza, COVID-19 and respiratory syncytial virus (RSV) immunization programmes. Recognizing the contribution of these programmes to epidemic and pandemic preparedness and response, it outlines practical approaches, indicators, data systems and tools to support the generation of accurate, timely and comparable coverage estimates. The document explains the importance of vaccination coverage monitoring for assessing programme performance, identifying inequities in access, evaluating health and economic impact, and informing policy and investment decisions.
