Explanation:
Active immunisation :- It promotes the production of circulating antibodies against foreign antigens by injecting a small quantity of modified antigen into the bloodstream.
Passive immunisation:- It is the application of antibodies from an immune individual to non- immune patient. This treatment is used when an individual has been or probably will be, exposed to an infectious disease and there is insufficient time for active immunisation.

Explanation:
Active immunity is the immune response to a pathogen. It relies on the body making antibodies, which take time to mount an attack against bacteria or viruses. Passive immunity occurs when antibodies are introduced rather than made (e.g., from breast milk or antisera).
