The World Health Organisation's (WHO) Polio Eradication and Endgame Strategic Plan 2013–2018, is the long-term strategy aiming to eradicate polio from the world by 2018.
There are four objectives to deliver in the Plan and timelines can be viewed here.
Worldwide immunisation of children using oral polio vaccine (OPV) has reduced wild poliovirus cases by 99.9% since 1988. Although OPV is safe, on rare occasions the live virus can mutate into circulating vaccine-derived poliovirus (cVDPV).
Eradicating polio completely, requires elimination of both wild and vaccine-derived poliovirus. An objective of polio eradication is for all countries to use inactivated polio vaccine (IPV) in place of OPV.
On 17 April 2016, the worldwide synchronized change over from trivalent to bivalent OPV began; this is the first stage of objective 2 of the Polio Eradication and Endgame Strategic Plan 2013-2018.
