A) The vaccine causes an antibody response in the body.
B) The vaccine responds to an infection in the body after it occurs.
C) The vaccine is similar to an antibiotic that is used to treat an infection.
D) The vaccine actively attacks the microorganism.

Vaccines are an antigen preparation that produces an antibody response in a human to protect him or her from future exposure to the vaccinated organism. A vaccine does not respond to an infection after it occurs; it does not act like an antibiotic and does not actively attack the microorganism.
