The vaccine derived polio virus (VDPV) strain has not been seen in the country for long (around 5 years).  It has also been reported to be safe as no such positive cases been detected although the regional government wish to alarm emergency to avoid reach to neighbouring countries as well as in India. The government soon going to launch massive vaccination programme before it become pandemic.

Earlier the oral polio vaccination contained attenuated P1, P2 and P3 strains but as P2 strain not been communicated so far, the recent vaccines lack P2 strain. “In this case, the P2 strain is vaccine derived. Someone vaccinated 10 months to a year back released the strain through stool. Such rare cases happen when a child’s immunity is very low. To avoid such stray cases, that happens one in a million, the P2 strain is no longer given even in vaccines,” said Dr G Srinivasa Rao, chief programme officer, National Health Mission, Telangana was said to Times of India.

“We’ll be following WHO set standards during our programmes,” he added. As part of the special campaign, children aged between six weeks to three years will be given additional doses of the injectable polio vaccine (IPV). Booths will be set up in areas being covered in these campaigns.

Officials informed that they will not deploy teams for door to door vaccination rather will encourage people to bring their children at vaccine booth which will provide additional information and protection against all kinds of polio strains.
