LO (3.75 years old) and I got our first flu shots this year. Mine was a few weeks ago. I had a moderate reaction: Fever, body aches and head ache for about 8 hours.

LO had her shot yesterday. She woke up last night vomiting. Google tells me this is a sign of allergic reaction. She doesn't have a fever (99.5°), and no one else at school has a stomach bug.

Did anyone else ever experience vomiting after the flu vaccine?? (I'm waiting to hear back from our doc)

ETA: I know many people don't have a reaction. I'm specially wondering about vomiting afterwards.
