Vaccines do not prevent infection. Vaccines prepare the immune system to fight infection by allowing the immune system to produce antibodies to a specific invading organism, kill it, and remember it in the future. In vaccines, this organism is often weakened or dead. If the invading organism is found by the immune system in the future following immunization, the immune system remembers it and produces the specific antibodies needed to kill it quickly.

Are vaccines effective before or after infection?

Vaccines are used to prevent infection; to create immunity so you do not get the infectious disease if you are later exposed to it after the vaccination has rendered you immune. If you already have caught the infection, vaccines will not be needed since the infection itself will provide immunity once the sickness is over. Anti-viral medicines are used after an infection to lessen the symptoms and speed recovery. See the related questions below for additional information.
