Duque admitted that doing so will be difficult and only delay the implementation of the anti-polio vaccination drive. In August, the DOH had conducted the door-to-door vaccination campaign in Manila after the water system there yielded Type 2 vaccine-derived polio virus (VDPV). “In 2016, we shifted from trivalent vaccines to bivalent vaccines or for Types 1 and 3 polio virus. Duque said the WHO should have ascertained that polio vaccination coverage in the Philippines is already high before excluding the vaccines for Type 2 virus. Duque cited the vaccination programs for various diseases like measles, polio and diphtheria where implementation is primarily dependent on LGUs.
