Long-Term Circulation of Vaccine-Derived Poliovirus That Causes Paralytic Disease [PDF]

Journal of Virology, 2002
ABSTRACT Successful implementation of the global poliomyelitis eradication program raises the problem of vaccination against poliomyelitis in the posteradication era. One of the options under consideration envisions completely stopping worldwide the use of the Sabin vaccine.

Update on Vaccine-Derived Poliovirus Outbreaks — Worldwide, January 2018–June 2019 [PDF]

MMWR. Morbidity and Mortality Weekly Report, 2019
Certification of global eradication of indigenous wild poliovirus type 2 occurred in 2015 and of type 3 in 2019. Since the launch of the Global Polio Eradication Initiative (GPEI) in 1988 and broad use of live, attenuated oral poliovirus vaccine (OPV), the number of wild poliovirus cases has declined >99.99% (1).
