Hi my daughter is 3 years old and received the flu shot . Prior to the shot she was ok and very energetic,right after the shot she became lethargic and a fever set in at 103. Spoke with doctors office follow there treatment of acetametaphine and ibuprofen and this did nothing for the fever. Could she have contracted the flu or allergic reaction from the injection. In reading the cdc vaccine info it states there should be a concern if a child has a allergic reaction to antibiotics or eggs. My daughter has a specific allergic reaction to amoxicillin but is not allergic to eggs, what should we do
