Catch-up vaccination

Catch-up vaccination refers to vaccinating an individual who has missed receiving vaccines on time as specified in the national immunization schedule. This may be also referred to as "Late"/"Delayed"/"Defaulter" vaccination, or "Delayed"/"Late"/"Rescued" doses, depending on the national context.

Every country should have a catch-up vaccination policy and catch-up vaccination schedule, following WHO recommendations for interrupted or delayed vaccination: https://www.who.int/publications/m/item/table-3-who-recommendations-for-routine-immunization.

Data on catch-up policies and schedules help to better understand the extent to which catch-up opportunities are being offered through routine vaccination service delivery. These data are reported annually through the WHO/UNICEF Joint Reporting Form on Immunization (JRF). Country data is updated and available as received.
