Why will you not get sick from a vaccine?

It’s biologically impossible for you to catch the flu from being vaccinated,

That’s because the vaccine is constructed from a killed virus. Not only that, but also there are only a couple of proteins from that dead virus in the vaccine. So, nobody’s getting injected with a complete virus.

because the amount of the vaccine that is given is not enough to get you sick

2%? i tried finding the exact sorry if it's not 100% correct ; -;
