5. Securing a Polio-free World: Building Resilience for the Switch

Learn about the safety nets being put in place to make sure that the phased withdrawal of the oral polio vaccine will speed up our journey towards a polio-free world, such as the introduction of the inactivated polio vaccine into routine immunization programmes.
This is one of a series of six videos on what is being done to secure a polio-free world: from the vaccines that are being used to stop polio; to how the oral polio vaccine is being phased out from April 2016 to remove any risk of vaccine-derived polioviruses, starting with the switch from trivalent to bivalent oral polio vaccine in April 2016; and how securely containing polioviruses within laboratories and vaccine manufacturing sites will keep every last child protected, long into the future.
