The Indian High Commission in Islamabad on Tuesday necessitated travelers from Pakistan travelling to India to submit oral polio vaccination certificate four weeks before their journey to India.

“Travelers from Pakistan to India after January 30 will require carrying their vaccination record as evidence of polio vaccination. They will be requested to show their record of vaccination for entry into India, and carry out throughout their stay in India” said the statement issued from Indian High Commission in Islamabad on Tuesday.

The format of Oral Polio Vaccination (OPV) certificate is available at the high commission’s official web site, the statement said.

“The step was being taken to safeguard India’s polio-free status, attained after sustained efforts and investment,” the high commission had said, adding that it was applicable to all travelers from all countries where polio disease is endemic or where cases of polio are reported.
