Question

The flu vaccine activates adaptive immunity. How does this occur?

A vaccine introduces
a weakened flu
virus into the body.
Antibodies are produced,
which bind to
the weakened flu virus
and signal immune cells
to destroy it.
Antibodies are quickly
produced and allow the
body to fight off
the infection.
The actual flu virus
enters the body,
and lymphocytes recognize
the antigens.
The immune system
identifies antigens
on the weakened flu virus.

Answer 4

The purpose of a vaccine is to inroduce the virus antigens to the body *before* you're exposed to the actual virus, so your body learns to recognize the antigens so it can fight them off in the future. Therefore, logically, the first step is:

A vaccine introduces
a weakened flu
virus into the body.

With that in mind, which step do you think is next? Remember that the purpose of the vaccine is to expose your body to the viral antigens.
