Question

Memory cells generated by vaccines include:

विकल्प

• Only memory T-cells

• Only memory B-cells

• Memory B-cells and T-cells

• Neither B-cells nor T-cells

Answer 1

Vaccines generate both memory B-cells and T-cells. On subsequent exposure to the pathogen, these memory cells recognise it quickly and produce a large number of antibodies to neutralise the invaders, enabling a faster and more robust immune response.
