 The Adamawa state government has confirmed the re-emergence of vaccine-derived poliovirus type 2 in the state. Professor Abdulai Issa, the state commissioner for health and human services, announced this during the flag-off of first-round outbreak response immunization on Saturday in Yola. Issa described vaccine-derived poliovirus 2, VDPV, as a strain of the weakened poliovirus that was initially included in oral poliovaccine, OPV. He expressed concern that the current resurfacing of the virus in the state was a great challenge and danger for possible outbreak of the transmitted virus. Record out Nigeria was declared free and safe from poliovirus in August 2020.
