Explain Polio
Adults who have not previously been immunized against polio should receive a primary series of inactivated polio vaccine (IPV) if traveling to areas where polio is endemic (Africa and the Indian Subcontinent) or to areas with documented outbreaks. Previously unimmunized children should also receive a primary series of lPV. If protection is needed within 4 weeks, a single dose of IPV is recommended. Travelers to risk areas who have previously completed a primary series and have never had a booster should receive a booster dose of IPV.
