Vedclass · Answer

(A) The principle of immunization or vaccination is based on the property of 'memory' of the immune system.When a vaccine is introduced into the body,the immune system recognizes the pathogen (antigen) and produces antibodies.Crucially,the immune system also generates memory $B$ and $T$ lymphocytes.These memory cells retain the information about the pathogen.If the same pathogen attacks the body again in the future,these memory cells recognize it immediately and mount a massive immune response,neutralizing the pathogen before it can cause disease.
