World Immunization Week
World Immunization Week is celebrated during the last week of April, and is sponsored by the World Health Organization (WHO).
World Immunization Week aims to promote the use of vaccines to protect people of all ages against disease. Immunization saves millions of lives and is widely recognized as one of the world’s most successful and cost-effective health interventions. Today, there are still 19.4 million unvaccinated and under-vaccinated children in the world.
