A Vaccine

Question

A vaccine
A) is a gamma globulin.
B) conveys active immunity.
C) contains antibodies.
D) is the same as an antitoxin.

Accepted Answer

A vaccine conveys active immunity, meaning it stimulates the body's own immune system to produce antibodies against a specific pathogen. Unlike gamma globulin or antibodies, a vaccine does not contain pre-formed antibodies. An antitoxin is a type of antibody that is given after exposure to a toxin, while a vaccine is given before exposure to a pathogen to prevent infection.
