How Disease Affects the Vaccines Effectiveness
One of the outcomes of flu vaccination is that the human body builds strong defensive antibodies. Thus, the immune response can be defective when your body is dealing with yet another infection (i.e., flu or a cold).
Less security may result from the shot, although it does not mean it won’t function at all.
Quote from CDC:
“Vaccination should be deferred for persons with moderate or severe acute illness until the illness improves.” — CDC Immunization Guidelines
Can You Get Sick From Flu Shot?
Commonly believed: Can you get sick from the flu vaccine?

- Slight fever
- Fatigue
- Muscle soreness
- Muscle aches
These symptoms point to your immune system’s action.

Do You Get Sick After Flu Shot?
Many people wonder: Can you get sick if you get the flu shot?
Pain or mild fatigue are examples of normal, temporary, and moderate symptoms that often last one to two days.
Although this phenomenon is rare, you are supposed to call your doctor in case you experience some severe reactions to your vaccine (e.g., high fever or difficulty breathing).
The cold, gastrointestinal disorder, or any other virus that is unrelated to the flu, is still capable of infecting you even after your vaccination. Vaccines do not prevent every disease. The flu vaccine, in particular, would be there to vaccinate against influenza viruses, of which it feels that they are highly probable to exist during the season.
Why? If your immune system is already fighting off another virus, it may not respond to the vaccine as well. You can also feel worse if your body is already worn out from the shot.
