Avaccine-derived poliovirus (iVDPV) was reportedfrom an immunodeficient child in the national capital region recently. The occurrence of an iVDPV is an extremely rare phenomenon and only about 100 cases with immunodeficiency have been documented to be excreting iVDPVs globally since 1961.
India continues to remain free of wild poliovirus. The occurrence of this case should not be confused with the wild poliovirus that was responsible for paralysis of thousands of children each year until it was eradicated from India in 2011.An iVDPVcan occur in a person with a rare immunodeficient disorder because the bodydoes not initiate an immune response to the vaccine as a healthy child would.
Ongoing poliovirus surveillance, including environmental surveillance, through sewage sample testing in the area has not revealed any poliovirus circulation in the area.In line with theglobal guidelines of WHO for response to VDPVs to mitigate the risk of spread of the VDPV, the Ministry of Health and Family Welfare conducted a polio round from 6th November,2015 to immunize all children under 5 years, in the vicinity of the area where the case was detected.
India along with ten other countries of South East Asia region of WHO has been certified polio free on 27 March 2014. The last case due to wild poliovirus in India was detected on 13 January 2011 andIndia continues to remain free of wild polio virus as certified by the Regional Certification Commission of South East Asia Region.
