evidence: The annual report (2017-18) of the Ministry of Health & Family Welfare (MoHFW) states that ‘there are three types of Polio viruses namely type-1, 2 and 3 for which the vaccine was provided under Universal Immunization Programme as trivalent oral polio vaccine. Since last case of wild polio virus type-2 was reported in 1999, therefore, Global Polio Eradication Initiative (GPEI) has recommended switch from trivalent OPV to bivalent OPV (containing only type-1 & 3). The tOPV to bOPV switch happened in India on 25th April, 2016. As part of Global Polio end-game strategy, to mitigate the risk associated with tOPV to bOPV switch, MoHFW has introduced Inactivated Polio Vaccine (IPV) in UIP in November, 2015, which was expanded across the country by June, 2016. Currently, two dose fractional schedule is being followed in the country with vaccination at 6 weeks and 14 weeks of age. Till December, 2017, around 3.45 crore doses of IPV have been administered to children across the country since its introduction’. [...] Fact: MoHFW has introduced Inactivated Polio Vaccine (IPV) in UIP in November, 2015, which was expanded across the country by June, 2016. 4.56 crore doses of IPV have been supplied to the state governments and 3.45 crore doses administered till December 2017. Since the claim was made in May 2018, the number might have reached the 4 crore doses. Hence, the claim is TRUE. However, this shift to IPV is part of the larger global movement against Polio and as mandated by GPEI.
