Vedclass · Answer

(A) Vaccination works on the principle of immunological memory. When a vaccine is introduced into the body,it mimics the pathogen,triggering the immune system to produce $B$ and $T$ memory cells.These memory cells recognize the specific pathogen upon subsequent exposure and mount a rapid,massive immune response by producing large quantities of antibodies,thereby neutralizing the pathogen.Thus,Assertion $A$ is true because vaccination provides protection,and Reason $R$ is true because it correctly explains the mechanism of immunological memory involving $B$ and $T$ cells.

Assertion $A$: Vaccination protects an individual against infection by specific pathogens.
Reason $R$: $B$ and $T$ memory cells produce antibodies in large quantities to neutralize the pathogen attack.
Which option is correct for Assertion $A$ and Reason $R$?
