← Human Body & HealthIf a flu vaccine with adjuvant is administered, which consequence follows regarding immune cell differentiation?
A)Naive B cells become plasma cells
B)Memory B cells rapidly expand✓
C)T helper cells become cytotoxic
D)Macrophages suppress antibody production
💡 Explanation
The flu vaccine, particularly one with an adjuvant, stimulates memory B cell expansion because adjuvant promotes enhanced antigen presentation and co-stimulation. Therefore, a robust secondary antibody response is achieved, rather than direct differentiation of naive B cells, or immune suppression.
