UNICEF, WHO laud India's polio-free status, says 'all govt-vaccines safe'
In a joint statement issued today, UNICEF and WHO said the risk of children getting vaccine-derived poliovirus was "minimal" in India because of high routine immunization coverage in the country.
'India continues to remain vigilant against all types of polioviruses'
The two global agencies also asserted that all vaccines provided under the Universal Immunization Program (UIP) are safe and urged people to get their children vaccinated.
"Certified polio-free in March 2014, India continues to remain vigilant against all three types of polioviruses. The last polio case due to wild poliovirus in the country was detected on 13 January 2011," the statement said.
Type 2 polivirus containing vaccine has been phased out globally
The agencies said type-2 poliovirus containing vaccine has been phased out globally, and in India, in April 2016, as part of polio endgame strategy. Like in other countries, bivalent oral polio vaccine (bOPV) has replaced the trivalent OPV (tOPV) in all polio campaigns in India.
