World Immunization Week


World Immunization Week, celebrated globally each year in April, highlights the importance of vaccines in offering protection to people of all ages against many diseases. This year’s campaign comes at an especially critical time as the COVID-19 pandemic has disrupted essential health services, including routine immunization, setting back progress by more than a decade.

During the pandemic, COVID-19 vaccination has underscored the importance of vaccinating people at high risk, including older people, health care workers and people with co-morbidities.


The objectives of this year’s campaign are to:


  • Raise public awareness of the protection provided by vaccines against disease and death throughout the life course.
  • Create support among health care professionals for life course vaccination.
  • Engage health policy-makers and managers of vaccination programs in endorsing a life course approach to vaccination.
