A major regional health milestone was the celebration in 2012 of the 10th anniversary of Vaccination Week in the Americas (VWA), the Region's largest Pan American health initiative. Including 44 million men, women, and children targeted in 45 countries and territories in 2012, VWA is estimated to have reached a total of more than 400 million people in its 10-year lifespan.

Thanks in large part to interest generated by VWA and to active outreach by its supporters, a growing number of WHO regions launched their own vaccination weeks during the decade. The culmination of all these efforts—and the realization of a global health dream—was the participation of more than 180 countries and territories from all six WHO regions in the first-ever World Immunization Week in 2012.
