\nIn immunisation (vaccination), a weakened or inactive form of an infectious agent or its components is introduced into the body. This triggers the body’s immune system to recognize the agent and produce antibodies and memory cells against it. If the vaccinated individual is later exposed to the actual infectious agent, the immune system can quickly recognize and eliminate it, thus killing the infectious agent through the immune response.
\n<\/section>\n
\nImmunisation works by stimulating the adaptive immune system to build memory against specific pathogens.
\n<\/section>\n
\nOption A is incorrect because vaccine components themselves do not directly kill the infectious agent; they are signals for the immune system. Option C is incorrect as immunisation is a highly effective method for preventing many infectious diseases. Option D is incorrect because immunity is specific; a vaccine against one disease typically provides protection only against that specific disease or a closely related group of diseases.
