Visualization of the Evolution and Transmission of Circulating Vaccine-Derived Poliovirus (cVDPV) Outbreaks in the African Region [PDF]

Bio Protoc
Since the creation of the Global Polio Eradication Initiative (GPEI) in 1988, significant progress has been made toward attaining a poliovirus-free world. This has resulted in the eradication of wild poliovirus (WPV) serotypes two (WPV2) and three (WPV3)

Detection of vaccine-derived poliovirus type-3 in sewage of Kathmandu Valley, Nepal

Clinical Infection in Practice
Enteroviruses include polioviruses, which are classified into three types: type 1, type 2, and type 3. The oral polio vaccine (OPV), which contains attenuated strains of these three types, has been pivotal in reducing polio incidence worldwide.

Evolution of a rare vaccine-derived multirecombinant poliovirus

Journal of General Virology, 2005
Recombination is one of the mechanisms by which viral genomes evolve. A vaccine-derived multirecombinant poliovirus strain was isolated from a 5-month-old child with vaccine-associated paralytic poliomyelitis after oral poliovirus vaccine administration. The isolate had an S2/S1/S2/S1 primary genomic structure as revealed by restriction fragment length
