The globally synchronized switch-another milestone toward achieving polio eradication
Wassilak SG , Vertefeuille JF , Martin RM . JAMA Pediatr 2016 170 (10) 927-928 To avoid the risks for vaccine-associated paralytic polio1 and circulating vaccine-derived poliovirus (cVDPV) outbreaks,2 the Polio Eradication and End-game Strategic Plan3 2013-2018 directs the phasing out of all oral poliovirus vaccine (OPV) use after wild poliovirus (WPV) is eradicated. This has started with the type 2 component in the vaccine. From April 17 through May 1, 2016, 155 countries using trivalent OPV (tOPV) (Sabin strains of types 1, 2, and 3) in their national immunization schedules removed it and introduced bivalent OPV (bOPV) (Sabin strains of types 1 and 3).3 This massive public health event required the engagement of every health facility providing vaccines in each of these countries. This unprecedented, synchronized vaccine introduction and withdrawal is termed the switch.4,5 | The switch was only possible owing to the efforts of thousands of health care professionals working in a coordinated manner across the globe. Successful implementation of the switch required extensive planning by national governments in partnership with Global Polio Eradication Initiative (GPEI) partners (World Health Organization [WHO], United Nations Children’s Emergency Fund, Rotary International, the Bill and Melinda Gates Foundation, and the US Centers for Disease Control and Prevention) in collaboration with Gavi, the Vaccine Alliance, and other key stakeholders and partners. Independent monitors in each country, both national and international, visited health facilities and vaccine stores to check that tOPV was no longer being stored and that bOPV was in stock for use. |
