Health Talk | Understanding vaccine-derived polio and its implications

Hindustan Times  

Last week, a two-and-a-half-year-old child in Meghalaya’s West Garo Hills tested positive for poliomyelitis, commonly known as polio. Vaccine-derived poliovirus is a strain of poliovirus that has mutated from the strain originally contained in oral polio vaccines. However, the reporting of vaccine-derived cases does not indicate the return of wild polio, which was officially eradicated in India in 2014, as declared by the World Health Organization. Wild poliovirus circulation remains a significant concern, especially as neighbouring countries like Pakistan and Afghanistan still report wild polio cases. While vaccine-derived polio is rare and not as alarming as wild poliovirus, the ultimate goal remains the eradication of both forms of the virus.
