Vaccine Derived Poliovirus (VDPV). [PDF]
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.

Prolonged Excretion of Poliovirus among Individuals with Primary Immunodeficiency Disorder: An Analysis of the World Health Organization Registry [PDF]
Individuals with primary immunodeficiency disorder may excrete poliovirus for extended periods and will constitute the only remaining reservoir of virus after eradication and withdrawal of oral poliovirus vaccine.

Importation and Circulation of Vaccine-Derived Poliovirus Serotype 2, Senegal, 2020–2021 [PDF]
Environmental surveillance for poliovirus is increasingly used in poliovirus eradication efforts as a supplement to acute flaccid paralysis (AFP) surveillance. Environmental surveillance was officially established in 2017 in Senegal, where no poliovirus

Recombinant Vaccine–Derived Poliovirus in Madagascar
To the Editor: Between October 2001 and April 2002, five cases of acute flaccid paralysis associated with vaccine-derived poliovirus (VDPV) type 2 isolates were reported in the southern province of the Republic of Madagascar. The first patient, an 11-year-old child from the urban district of Toliara, first experienced paralysis on October 29, 2001 ...

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

Stem Cell Transplant in Immune-deficiency-associated Vaccine-derived Poliovirus. [PDF]
Abstract Patients with severe primary immunodeficiency are at risk for complications from live-attenuated vaccines. Here, we report a case of a vaccine-associated paralytic polio and Bacille Calmette-Guérin disease in a 6-month-old girl with severe combined immunodeficiency resulting from homozygous recombinant activating gene 1 ...

Update on Vaccine-Derived Poliovirus Outbreaks - Worldwide, January 2020-June 2021. [PDF]
As of May 1, 2016, use of oral poliovirus vaccine (OPV) type 2 for routine and supplementary immunization activities ceased after a synchronized global switch from trivalent OPV (tOPV; containing Sabin strain types 1, 2, and 3) to bivalent OPV (bOPV; containing Sabin strain types 1 and 3) subsequent to the certified eradication of wild type poliovirus (

Update on Vaccine-Derived Poliovirus Outbreaks - Worldwide, January 2023-June 2024. [PDF]
Circulating vaccine-derived polioviruses (cVDPVs) can emerge and lead to outbreaks of paralytic polio as well as asymptomatic transmission in communities with a high percentage of undervaccinated children. Using data from the World Health Organization Polio Information System and Global Polio Laboratory Network, this report describes global polio ...

Early detection of a circulating pre-vaccine-derived poliovirus type 1 (pre-VDPV1) variant linked to an acute flaccid polio case prior to VDPV1 emergence, Israel, 2024 to 2025 [PDF]
We report the emergence and evolution of a circulating vaccine-derived poliovirus type 1 (cVDPV1) outbreak in Israel, linked to a vaccine-associated paralytic poliomyelitis case.
