For example, in [[vaccination]]s, a human is exposed to an artificially weakened [[virus]] in order to stimulate the body's [[immune system]] to produce [[antibodies]] that fight the virus. Then, when the live virus is encountered, the body can vigorously defend against it, already having produced the relevant antibodies. See [[pre-exposure prophylaxis]].
