How is OPV Different from Inactivated Polio Vaccine (IPV)?
OPV and IPV are both designed to protect against polio but differ in their composition and administration:
OPV is a live attenuated vaccine given orally, whereas IPV is an inactivated vaccine administered via injection. OPV provides better intestinal immunity, while IPV induces strong humoral immunity. IPV is safer for immunocompromised individuals.
