Question:
What do you mean by active and passive immunisation ? [SAll – 2015]
Answer:
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.
