      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.

      Learn about the switch from trivalent bivalent oral polio vaccine in April 2016 - the biggest, globally-synchronised project in the history of vaccines - and why gradually phasing out the oral polio vaccine is essential to prevent the emergence of circulating vaccine-derived polioviruses in the future.

      In order to secure a polio-free world for all future generations, we must eradicate all strains of the virus. Learn about wild polioviruses and vaccine-derived polioviruses, and what needs to be done to stop both strains for good.

      Two vaccines have brought us to the brink of a polio-free world: the oral polio vaccine and the inactivated polio vaccine. Learn how these vaccines work and the different, complementary roles they have to play in delivering a polio-free world. 
      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.

      This series of six videos explain the important steps that are being taken to make sure that, once the poliovirus has been eradicated, it will never have the opportunity to return. We have never been closer to achieving our goal; but there is much still to be done to secure a polio-free world. 
      Once wild polio has been eradicated, the only risks of the virus returning would come from rare strains of circulating vaccine derived polioviruses, and from potential leaks of the virus from laboratories or vaccine manufacturers. This series of videos will explain the work being done to address these risks: 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.
