Strengthening routine immunization is a pillar of the polio eradication strategy.
High routine immunization coverage establishes a strong base for population immunity to prevent polio outbreaks and builds a sustainable platform to introduce the Inactivated Polio Vaccine (IPV) and deliver other lifesaving vaccines.
In polio endemic countries, the virus persists in marginalized populations, and in areas where health systems and immunization services are largely non-existent or ineffective in reaching the eligible population and oversight and management are weak.
These countries also contain many of the world’s under-vaccinated children
