Injectable polio vaccine (IPV) in India from 2015
After using oral polio vaccine for decades, India is all set to 
introduce Injectable Polio vaccine (IPV) from next year. While India has
 been certified polio free by the World Health Organisation last week, 
the certification of the region comes as countries prepare for the 
introduction of inactivated polio vaccine (IPV) in routine immunisation 
as part of the eventual phasing out of oral polio vaccines (OPV). More 
than 120 countries currently use only OPV. According to the experts 
these countries will have to introduce a dose of IPV in 2015 as part of 
their commitment to the global polio endgame plan which aims to ensure a
 polio-free world by 2018.
In a bid to ensure complete elimination of
 the polio virus, the India Expert Advisory Group on polio had too 
recommended of stop using trivalent polio vaccine which it has been 
using for more than three decades. 
The need was felt as chances of 
vaccine derived polio virus infection (VDPV) are higher with the use of 
TOPV (that targets all three strains of polio virus P1, P2 and P3).
