Does the flu shot weaken your immune system?
Getting a flu shot does not weaken your immune system and make you more likely to get the flu. Getting a flu vaccine prepares your immune system for the flu. A flu vaccine teaches your immune system to recognize that virus as a threat.

Are all flu shots the same quality?

Does the flu shot shorten the duration of the flu?
It’s to protect you from the severity of the infection. If you get the flu without a shot, you’ll have symptoms for 5 to 14 days. If you get the flu shot and still contract the flu, the flu shot will shorten the duration of that infection so you’re only ill a fraction of the time.
