Vaccine-derived polio case in Meghalaya: India's polio-free status not jeopardized
• A two-year-old child in Meghalaya tested positive for vaccine-derived polio, a rare occurrence triggered by the oral polio vaccine (OPV).
• The OPV can lead to vaccine-derived infections in children with weak immune systems, causing severe infection.
• India's last reported case of wild poliovirus was in 2011, and it was declared polio-free in 2014.
• Despite vaccine-derived polio cases, India's polio-free status remains as long as wild poliovirus is not detected.
