Which vaccine requires injection?

Explanation:
Routes of administration distinguish these vaccines. IPV is given by injection (usually intramuscular or subcutaneous) because it uses inactivated virus that requires parenteral delivery to elicit systemic immunity. OPV is administered orally as drops, since it’s a live attenuated vaccine that works in the gut and through mucosal immunity. So, the vaccine that requires injection is IPV.
