Vedclass · Answer

(A) Live attenuated vaccines contain weakened forms of the pathogen. These vaccines are highly effective because they mimic a natural infection,stimulating both humoral and cell-mediated immune responses,which often leads to long-lasting immunity.$Peyer's$ patches are indeed secondary lymphoid organs located in the small intestine. They play a crucial role in mucosal immunity by sampling antigens from the intestinal lumen and initiating an immune response. Oral vaccines (often live attenuated) stimulate these patches,providing robust local and systemic immunity.Therefore,both the Assertion and the Reason are correct,and the Reason correctly explains why live attenuated vaccines are effective.

$A$: Live attenuated vaccine is better in terms of immunity provided to the recipient.
$R$: As secondary lymphoid organs,example $Peyer's$ patches are stimulated to protect the individual.
