IPV Introduction, OPV Withdrawal and Routine Immunization Strengthening

This site provides information on objective 2 of the Polio Eradication and Endgame Strategic Plan. It contains the rationale for and resources related to the introduction of Inactivated Poliomyelitis Vaccine (IPV), withdrawal of Oral Polio Vaccine (OPV) and routine immunization strengthening.

The Strategic Plan was developed in response to the May 2012 World Health Assembly which declared the completion of poliovirus eradication to be a programmatic emergency for global public health. Under this plan to achieve and sustain a polio-free world, the use of OPV must eventually be stopped worldwide, starting with OPV containing type 2 poliovirus (OPV type 2). At least one dose of inactivated polio vaccine (IPV) must be introduced as a risk mitigation measure and to boost population immunity.
