Question 43
F

A person is already ill with a bacterial infection. Why would giving them a vaccine against that bacterium not be a useful treatment?

[1]
A

A vaccine is effective only against viruses, so it has no effect on a bacterium

B

A vaccine takes several days to produce antibodies, so it would act too slowly

C

A vaccine contains antibodies that are destroyed by the live bacterium present

D

A vaccine would make the person more ill by adding live bacteria to the body
