My daughter has been vomitting every day for four weeks after having the vaccine for the HPV virus. The vomitting started the same day. She has seen four different dr.'s who find nothing wrong with her, but all say it has nothing to do with the vaccine. She is not feeling sick otherwise, and the vomitting is at very random times. Has no correlation with eating or activity, and she does it anywhere from 1 to 3 times a day. Anti nausea meds are not a good answer since the effects of them would outway the problem. Do you have any valuable info for me and how concerned should I be. She continues to eat and has lost no weight. She just turned 10.
