Vedclass · Answer

(A) The principle of vaccination is based on the property of 'Memory' of the immune system.During vaccination,an inactivated or weakened pathogen (vaccine) is introduced into the body.The immune system recognizes the antigen and produces specific antibodies against it.Crucially,the immune system also generates memory $B$ and $T$ cells.When the body encounters the actual pathogenic agent later,these memory cells recognize the pathogen immediately and produce a massive amount of antibodies to neutralize the infection.Therefore,the correct option is $A$.
