Can you still get sick if you've had your flu shot?

Yes: The flu shot is relatively good at protecting you from the strains that make up the vaccine as long as you receive it 2 or more weeks before exposure.During any flu season there are flu strains that were not placed in the vaccines ( 3 in vac/max) and you can catch those if exposed. Next yr their may be a 4 strain vaccine but in the past the >3 strain vaccines had limited protection.

A/W Dr. Ferguson: You may or not be protected against that particular strain. It usually takes 2 weeks to be effective. If you do get it - it is usually attenuated if strain you were vaccinated against.

Yes: Some symptoms .... Licold and flu are expected after shot.

Confusing question: Not all strains of flu make it into the vaccine so some may get a flu from one of these other strains even if they got a "flu" shot early on. You can also have a mild to moderate systemic reaction to the vaccine if you are allergic to eggs or any other component in the vaccine. Last but not least, you can get ill from something unrelated to the flu shot that you were incubating when you got it.
