The Immunization Summary is an app for visualizing data (tables, graphs, maps) on policies, activities and impact of national immunization systems. These data are reported by WHO & UNICEF Member States annually for incidence, coverage, immunization system indicators and vaccination schedules.

The WHO-UNICEF estimates of national immunization coverage constitute an independent technical assessment of coverage.

Data are available from 1980 to 2019 (as of July 2020) for 195 countries or territories.
Data from 1980 to 2020 will be available in July 2021.

The app is currently available in the six official WHO languages.
