The Philippines will roll out a series of synchronized oral polio vaccination campaigns in October—targeting children under age 5 in at-risk areas. The country declared a polio outbreak in mid-September after confirming two vaccine-derived poliovirus type 2 cases in children and finding the virus in sewage in two provinces. The outbreak is the first in the country since WHO awarded it polio-free status 19 years ago. Philippines DOH;Philippines DOH
