UNICEF-WHO Philippines: Polio Outbreak Situation Report #2 (30 September 2019)
On 19 September 2019, the Philippines Department of Health (DOH) declared a polio outbreak after 2 confirmed polio cases of vaccine-derived poliovirus type 2 (VDPV2). Environmental samples taken from Manila and Davao also tested positive for VDPV2, as well as for VDPV1.
Because circulating VDPV2 (cVDPV2) is highly contagious and expected to spread rapidly among unvaccinated children, cVDPV2 response is being prioritized over response to VDPV1.
DOH is planning 3 rounds of vaccination targeting under-five children in Mindanao with monovalent Oral Polio Vaccine (mOPV) for poliovirus type 2, scheduled for mid-October (Lanao del Sur and Davao del Sur including Marawi and Davao city), mid-November 2019 (All of Mindanao regions) and January 2020 (All of Mindanao regions). Sufficient quantities of mOPV2 are currently being sent from the global vaccine stockpile, by the Global Polio Eradication Initiative (GPEI).
Enhanced routine immunization with bivalent Oral Polio Vaccine (bOPV) targeting poliovirus type 1 and 3, as well as inactivated poliovirus vaccine (IPV) targeting all 3 types of polio is ongoing1 .
DOH is planning a bOPV vaccination campaign in the National Capital Region (NCR) for children under 5.
