Flu shot side effects
Younger children can experience some side effects from the flu shot. So can all the others but it happens mostly to the youngsters, especially if they are having the shot for the first time. These side effects are not nearly severe. Soreness and pain may occur at the spot where the shot was given. It may even swell up a bit but will normally go away in 48 hours. Fever, rash and even muscle ache can be the side effects of a systemic flu shot. These reactions will occur some 6 to 12 hours after the shot and will last for a day or two. Hives, angioedema and anaphylaxis are really serious allergic reactions, even life-threatening. Luckily, they are pretty rare. This happens to people allergic to eggs because of the egg proteins in the shot.

Is it just a coincidence?
When trying to figure out whether the symptom is from the shot, people should take some things into consideration. For instance, if a child had a couple of flu shots before and did not experience the reaction, than it is more likely that the illness is caused by something else and not by the flu shot. Another thing to consider is how long after the shot the child got sick. Flu shot reaction occurs in the first 6 to 12 hours. If the child already had a cough or a runny nose and develops a fever after the shot, than it is not because of the flu shot. Because of this it is always best to wait for the child to get better before getting the flu shot. It is important to have in mind that simply because two things happened around the same time does not mean that one caused the other.
