I keep getting “Active vs passive immunity” questions wrong in Human Health and Disease. What's the trap?
calling a vaccine passive immunity.
The usual trap: calling a vaccine passive immunity. How to avoid it: vaccine = active (you make it); antiserum and mother's milk = passive (given ready). Go back to the definition — active immunity is made by your own body after infection or a vaccine (lasting); passive immunity is ready-made antibodies given from outside (quick but short-lived).
