In brief: No

No. The virus in the vaccine is not a live virus and cannot cause the flu.

Notable exception- Flumist. This is a live attenuated influenza vaccine (LAIV)

In brief: No- it activates....

The flu shot causes an immune response that is similar but less intense reaction compared to the real flu (fever, mild myalgias, arthralgias) .
This is expected and should not deter you from getting the flu shot because the reaction is reassuring you that your immune system will be strong enough in the future to create an immune response against the real flu virus.
