Описание к видео What is Vaccine Derived Poliovirus (VDPV)?

Vaccine-derived poliovirus (VDPV) occurs when the weakened virus in the oral polio vaccine mutates and regains the ability to cause illness and paralysis. This typically happens in areas with low vaccination coverage, allowing the virus to circulate and evolve. Maintaining high vaccination rates is crucial to prevent VDPV outbreaks and protect communities.
