Polio Vaccine

Medical concept

About

Polio vaccines are crucial for preventing poliomyelitis, a serious infection that can cause paralysis and death. There are two main types: the inactivated poliovirus vaccine (IPV) given by injection and the oral poliovirus vaccine (OPV), which is live and attenuated. IPV is commonly used in developed countries due to its safety profile and effectiveness in inducing long-term immunity. It is administered in a series of doses, typically starting at two months of age, with subsequent doses given at intervals of at least four weeks. For travelers visiting areas with ongoing polio transmission, ensuring full vaccination against polio is essential. Adults who have completed the primary series may require a booster dose if traveling to high-risk areas. The vaccine works by stimulating the body to produce antibodies against the poliovirus, thus preventing infection. While polio has been largely eradicated in many parts of the world, ongoing transmission in some regions necessitates continued vaccination efforts to protect individuals and communities.
