human
I've had the flu shot the past 2 years at my company without incident. I've never had any major side effects. I wait the 15 minutes and happily leave.This year, about 5 minutes after the flu shot (where I felt normal), I suddenly felt very nauseous and then fainted for approx. 10 seconds. I wasn't anxious about getting the shot. I look away while I get it, but I wasn't nervous. After 5 minutes, I had stopped thinking about it. Why did I react this time? It's really bothering me that this occurred.

Hi, it may be the allergic reaction to the vaccine of this brand, or may be out dated, or if you are on empty stomach at that time, you can have such a symptom. As you have recovered automatically with out any treatment and didn't need any treatment there after, it should a physiological incidence.                        Next time when you have any injection eat  some thing and then have the injection.                          Thank you.
