If you have had one or two doses of polio vaccine in the past you should get the remaining one or two doses. If you are fully vaccinated and are at increased risk of poliovirus exposure, including planning to travel to countries where there is an increased risk, you may receive a single lifetime booster dose of IPV.

Proof of polio vaccination at least 6 weeks prior to departure is required for visitors from polio-endemic and re-established transmission countries to apply for an entry visa for Saudi Arabia and travelers will also receive 1 dose of OPV at border points on arrival in Saudi Arabia.

OPV was recommended for use in the United States for almost 40 years, from 1963 until 2000. The results have been miraculous: Polio was eliminated from the United States in 1979 and from the Western Hemisphere in 1991. Since 2000, only IPV is recommended to prevent polio in the United States.

ISLAMABAD, May 26 (Xinhua) -- Pakistan reported its third polio case of the year after it was detected in a child in the country's southwest Balochistan province, the Pakistani Health Ministry said.
