Everyone travelling to countries with polio transmission should be up-to-date on their polio vaccinations.
Most adult Singaporeans who were born and grew up in Singapore since the 1960's would have had polio vaccinations as children, and are protected. Many NS men were given trivalent OPV at SAF enlistment.
Children < 18 years of age are protected if they have had ≥ 4 doses of polio vaccine.
Adults are protected if they already had an IPV booster at/after age 18.
Adults are protected if they already had an OPV booster at/after age 18, and it was given before May 2016.
Polio vaccine recommendations for adults will depend on destination, duration of travel, childhood polio vaccines taken, if they had a polio booster at/after age 18, and whether OPV was given after May 2016.
OPV from May 2016 onwards covers type 1 & type 3, but no longer includes type 2. IPV remains trivalent.
IPV is currently prioritized for those who need an adult booster because of travel > 4 weeks to the Philippines and certain African countries (Group C in table above) which have type 2 polio cases.
IPV is also needed for pregnant and immunocompromised travelers who cannot receive OPV safely.
