Flu Shot Symptoms
Reviewed: Dr. Mera
6. Fatigue
After a flu shot, some people will complain that they feel unusually tired and not feel like doing anything at all. Again, this is quite normal as it is caused as the body reacts to the vaccine so it is not anything to be concerned about usually.
Headaches are also fairly common after a flu vaccine has been administered and, again, this is not something you should worry about. The same goes for nausea, which is another symptom that will sometimes come after a flu shot. While these symptoms are not usually something to worry about, you should still speak with a doctor if they become severe.
