Brief note: Vaccines stimulate the immune system to make antibodies and memory immune cells (and often T‑cell responses) so the body can respond faster and stronger on future exposure. They do not change a person’s DNA, are primarily preventive (not for treating active illness), and are distinct from passive transfer of antibodies.
