Hashtags: #VaccinesWork, #Humanly Possible

World Immunization Week – celebrated in the last week of April brings together a diverse and broad coalition of partners to promote the use of vaccines to protect people of all ages against disease.

To ensure that the immunization successes of the past 50 years are built on in the next decades, WHO, UNICEF, Gavi, the Vaccine Alliance and other partners will continue the “Humanly Possible” campaign launched last year, with a future forward look on the ensuring Immunization for All is Humanly Possible.

As 2025 is the mid-point in the Immunization Agenda 2030, World Immunization Week will look at not only what immunization does to improve lives today but what immunization can achieve in the coming decades as more children are reached with essential immunizations and new vaccines are developed to protect against an even broader range of diseases across all ages.
