Re: WHO press release: Global eradication of wild poliovirus type 3 declared on World Polio Day

28 October, 2019

Hi Everyone,

This is good question. As per WHO recommendations and worldwide experience in responding to VAPP standard protocol is same as response to any WPV incident. This means using OPV to mop up the WPV or Vaccine Derived Polio Virus. The type of OPV either bOPV (bivalent type1 & 3) or mOPV (monovalent type 1 or 2 or 3) would depend upon the type of circulating virus and the risk factors in the specific geography and population.

Please refer to GPEI website for more details. <>
