Vaccination is a prophylactic measure that involves introducing a harmless or weakened pathogen into the body to stimulate an immune response and develop immunity against that pathogen. This protects a person from future attacks by the pathogen. Antiserum injections and artificial passive immunity involve administering pre-formed antibodies to protect against a pathogen after exposure has already occurred, and therefore are not prophylactic measures.
