I keep getting “Active vs passive immunity” questions wrong in Human Health & Disease. What's the trap?

calling a vaccine passive immunity.

The usual trap: calling a vaccine passive immunity. How to avoid it: a vaccine triggers your OWN antibodies → active; antivenom is ready-made → passive. Go back to the definition — active immunity is when the body makes its own antibodies; passive immunity is receiving ready-made ones.
