Vedclass · Answer

(C) Assertion $(A)$ is correct: Vaccines work on the principle of memory of the immune system. They induce the production of antibodies and generate memory $B$ and $T$ cells that recognize the pathogen upon subsequent exposure.Reason $(R)$ is incorrect: In vaccination,either weakened (attenuated) or inactivated (dead) pathogens,or antigenic proteins of the pathogen,are introduced into the body,not 'activated' pathogens. Introducing activated (virulent) pathogens would cause the disease.

$A$ - The vaccines generate memory $B$ and $T$ cells. $R$ - In vaccination,activated pathogens are introduced into the body.
