Which correctly compares the immunity produced by a vaccine with the immunity produced by injection of antibodies from an extern
al source? Injection of antibodies helps the body develop memory cells, which only produces a temporary immunity, whereas a vaccine can fight infection for years. A vaccine helps the body develop memory cells that make immunity last, whereas injection of antibodies only produces a temporary immunity. Injection of antibodies helps the body develop its own copies of the antibodies so immunity lasts, whereas a vaccine only produces a temporary immunity. A vaccine actively attacks pathogens until it is used up so immunity is temporary, whereas injected antibodies will remain passively in the blood, giving immunity for life.
For the answer to the question above, I believe the answer is <span>A. vaccine helps the body develop memory cells that make immunity last, whereas injection of antibodies only produces a temporary immunity.
