Be sure to mention to your primary care doctor, but if the fever was low or you just felt a little warm for awhile, it is probably the vaccine doing what it is meant to do.

These side effects are not due to the flu virus as is often a misconception. They are most likely to occur in the first 1-2 days and then stop. Studies show that only ~5% of people have fever and muscle aches.
Very often a healthy person can tolerate getting the flu, but they. can give it to one of the high risk groups mentioned above. This is the logic behind all people getting this important immunization!
a small dose of the flu so your immune system is going to work on creating resistance. Some vaccines are active and others are inactive but they basically create immunity the same way.
