Answer Posted / madhu
in simple words passive immunity is when you acquire immunity against a certain pathogen, disease, or condition without having your body exposed to the pathogen, disease, or condition. A good example is the baby acquiring passive immunity against common cold viruses by breast feeding. And another example is getting Anti-rabies shot after being bitten by a rabies-infected dog.
While active immunity on the other hand is acquiring immunity through exposure to the antigen(a molecule that stimulates an immune response). In which the body will have to develop the immunity it self by producing antibodies. However unlike passive immunity, this will take time.... But is usually permanent...:) An example of active immunity is acquiring immunity againt Chicken Pox after experiencing one episode.
