April 25, 2016: “National Switchover Day” from trivalent Oral Polio Vaccine (tOPV) to bivalent Oral Polio Vaccine (bOPV)

In routine immunization babies will get bOPV and not tOPV from 25th April and at third dose of oral polio vaccine (OPV) they will also be administered an injection with inactivated polio vaccine (IPV)

By that date all vaccines having three types of polioviruses will be destroyed. Type 2 virus will also be destroyed in all laboratories ( except Pune Virology Institute ) to eliminate the chances of its spread again.

The efficacy of bOPV will be five times that of tOPV because there will be only two viruses in the vaccine.

Type 3 virus would be removed from the vaccine as next step because not a single case of this virus had been reported from anywhere in the world during the past two years. By 2020 OPV will be completely stopped and only Inactivated Polio Vaccine, which is a dead virus, will be used all over the world.
