Immunization Week in the Western Pacific


Immunization Week initiatives began in the WHO Region of the Americas in 2003. The countries and areas in the WHO Western Pacific Region started participating in Immunization Week in 2011. The Immunization Week was observed simultaneously in WHO’s six regions for the first time in 2012, with the participation of more than 180 countries, territories and areas worldwide.

The World Health Assembly endorsed the World Immunization Week during its May 2012 meeting, alongside the Global Vaccine Action Plan. This event takes place during the last week in April every year which gives an opportunity for countries and partners to raise public awareness on importance of vaccine and immunization. It has been observed that a wide range of activities are implemented by countries in this Immunization Week globally and in our Region.
