What is the difference between naturally aquired passive immunity and naturally aquired active immunity?
Naturally acquired active immunity happens by exposure to a pathogen, infection, and recovery. If you get a bacterial infection and then recover, you are immune to that strain of bacteria from now on, because you made antibodies to it. Naturally acquired passive immunity is when antibodies are NOT made by you, but by someone else. This happens when a mother passes her own antibodies into the fetal bloodstream, and these antibodies can protect the baby.
