Year's first case of vaccine-derived polio reported in Bengal.

NEW DELHI: India has reported its first case of vaccine derived polio virus (VDPV) infection of 2012. A five-month-old child from the Murshidabad district of West Bengal has got infected with the virus after taking the oral polio vaccine.

This, however, does not threaten India's recently awarded polio free status because though detecting VDPV is part of the surveillance system, it does not get added when putting together a country's polio numbers.
