Vaccine-Derived Polio Circulation Persists in Nigeria, Experts Warn

In a concerning development, Nigerian virologists have warned that poor immunisation coverage and insecurity are fuelling the circulation of vaccine-derived poliovirus (VDPV) in the country. This alarming revelation comes despite Nigeria’s achievement of interrupting the transmission of indigenous wild poliovirus. The experts’ concerns were shared in a report published by Punch Newspapers on November 8, 2026.

According to the report, the continued circulation of VDPV is a cause for concern, as it poses a significant threat to Nigeria’s ongoing efforts to eradicate polio. The experts have urged increased immunisation coverage, improved sanitation, and enhanced security in vulnerable areas to combat this issue.

Nigeria had been making significant strides in polio eradication efforts, with the World Health Organization (WHO) certifying the country as polio-free in 2024. However, the continued circulation of VDPV indicates that more needs to be done to completely eradicate the disease.

This development is of particular importance to Nigerian readers, as polio eradication is a critical step towards ensuring the overall health and well-being of the nation’s citizens. It is essential that the government, healthcare providers, and the public work together to address this issue and ensure that Nigeria remains polio-free.
