Inactivated Polio Vaccine (IPV)
Polio is a disease caused by a virus. It enters the body through the mouth. Usually it does not cause serious illness. But sometimes it causes paralysis, and it can cause meningitis.
Before traveling to areas that have Polio circulation, travelers should ensure that they have completed the recommended age-appropriate polio vaccine series and that adults have received a single lifetime IPV booster dose. In addition, CDC recommends a single lifetime IPV booster dose for certain adult travelers to some countries that border areas with Polio circulation. These recommendations are based on evidence of historical cross-border transmission. These recommendations apply only to travelers with a high risk of exosure to someone with imported Polio infection. These travelers would include those working in health care settings, refugee camps, or other humanitarian aid settings.
