Vaccine Derived Poliovirus (VDPV). [PDF]

open access: yesLe infezioni in medicina, 2023
Poliomyelitis is caused by Poliovirus, a member of a large group of enteroviruses. Vaccine-derived polioviruses (VDPVs) stem from mutated live poliovirus, which is contained in the Oral Polio Virus vaccine (OPV). In addition, the emergence of VDPV is one of the global challenges for the eradication of poliomyelitis.

Update on Vaccine-Derived Poliovirus Outbreaks — Worldwide, January 2021–December 2022 [PDF]

open access: yesMMWR. Morbidity and Mortality Weekly Report, 2023
Circulating vaccine-derived poliovirus (cVDPV) outbreaks* can occur when oral poliovirus vaccine (OPV, containing one or more Sabin-strain serotypes 1, 2, and 3) strains undergo prolonged circulation in under-vaccinated populations, resulting in genetically reverted neurovirulent virus (1,2).

Asymptomatic immunodeficiency-associated vaccine-derived poliovirus infections in two UK children [PDF]

open access: yesNature Communications, 2023
AbstractIncreasing detections of vaccine-derived poliovirus (VDPV) globally, including in countries previously declared polio free, is a public health emergency of international concern. Individuals with primary immunodeficiency (PID) can excrete polioviruses for prolonged periods, which could act as a source of cryptic transmission of viruses with ...
