Polio Vaccines is administered to newborns and children in the United States as part of their standard immunizations regimen. A four-dose series of inactivated poliovirus vaccine (IPV) is provided by IM or SC injection at the ages of 2, 4, and 6-18 months, as well as at the age of 4-6 years. Since 2000, when a policy decision was taken to discontinue the use of oral polio vaccine in order to avoid the uncommon occurrence of vaccine-associated paralytic poliomyelitis from the attenuated live virus vaccine, IPV (Ipol®, Sanofi) has been the sole polio vaccine used in the United States. Outside of the United States, oral polio vaccination is still in use.
Adult travellers 18 years of age and older who are travelling to countries with recognized WPV circulation or to nations that border countries with WPV in circulation should receive a single lifetime IPV booster dosage. WPV circulation has been documented in Afghanistan, Pakistan, Middle Eastern countries, Egypt, Nigeria, and other Sub-Saharan African countries. Outbound long-term (4-week) visitors and inhabitants of WPV-affected countries may be asked to produce confirmation of Polio Vaccines between 4 weeks and 12 months before departure under WHO IHR to prevent infected travellers from bringing polio into polio-free countries. The CDC's website is routinely updated with information about which countries have ongoing polio transmission and which countries may demand confirmation of vaccination.
