History of World Immunization Day
World Immunisation Day was launched in 2012 by the World Health Organization (WHO) as part of a broader strategy to increase vaccination rates around the world and achieve universal immunisation coverage. It serves as a platform to remind governments and individuals of the critical role that vaccines play in preventing deadly diseases.
Historically, vaccination efforts have significantly decreased the incidence of many deadly diseases. The development of the smallpox vaccine in the 18th century led to the eventual eradication of the disease. In the 20th century, immunisation campaigns for polio, measles, and diphtheria, among others, led to significant reductions in global morbidity and mortality. The establishment of World Immunisation Day aims to continue this momentum by promoting continued progress in vaccine coverage and encouraging international cooperation.
