A 46-year-old male asked:

If a 3 year old gets a flu vaccination, are there going to be any side effects?

Sore arm: Her arm may hurt, she may have muscle aches, a low grade fever (99-100), she may be tired and cranky. Tylenol, (acetaminophen) ice cream, and sleep fix most of these, and all are better than actual influenza.

Possibly: Local skin reaction is the most common reaction. An intranasal option is also a possibility. Discuss the full risks and benefits with your pediatrician.

Can be: The side effects for a 3 year old are pretty much the same as for anyone else -- if it's a shot - soreness and mild pain around the injection site - some people get a milder flu-like illness for a couple days.

Maybe (not) . . .: Anyone of any age who gets anything done can suffer side effects from said thing whether medication or procedure. In general, benefit of flu vaccination outweighs possible harm. Of course there are also specific reasons not to get flu shot, eg egg allergy. Discuss your concerns w/your doc (or child's doc).
Dr. Robert Kwok
Pediatrics 33 years experience
Usually not: Most children around that age can get flu vaccinations without side effects, but a few will have a sore arm from the shot. The nasal spray vaccine sometimes causes a couple days of mild sniffles.
