[|Human|] My 6 year old son received his flu vaccine 9/23. On 10/4 he was lethargic, complaining of a stomachache and had a fever of 102. That evening he vomited three times and I gave him medicine to help him sleep. He has eaten little and continued to run a fever every day. He became congested on Monday 10/6. On 10/6 my 2 year old daughter began a fever. She had difficulty sleeping due to congestion. She has a limited appetite, mostly fluids, and has slept most of the day. I haven t taken them to the doctor. I believe this is a reaction to the flu vaccine and a mild case of the flu.
[|AI|]  Hi...this is not a reaction to flu vaccine. I feel with 2 kids in the family being affected - it should be a viral illness. Fever of few days without any localizing signs could as well a viral illness. Usually rather than fever, what is more important is the activity of the child, in between 2 fever episodes on the same day. If the kid is active and playing around when there is no fever, it is probably viral illness and it doesn't require antibiotics at all. Once viral fever comes it will there for 4-7 days. So do not worry about duration if the kid is active. Regards -
