Also known as: Polio drops · OPV
The oral polio vaccine (OPV) is given as drops by mouth and protects against the poliovirus. Because it is easy to administer and spreads immunity through communities, OPV has been central to global polio eradication efforts. It is given at birth and repeated several times in early infancy, often alongside the injectable IPV.
