My daughter got her shots on the 15th. She was behind because of a move and change in Drs. She had a fever for 24 hours, but then this...

She is vomiting in her sleep and having major diarrhea. I don't know if she is peeing at all because the diarrhea is so bad. We had her in the ER yesterday but they gave her fluids and sent her home, but it has been almost every night for 11 nights and every day for that time as well. She goes to the Dr tomorrow. She's barely eaten and has lost over a pound (close to 2) and I'm worried this is all related to the shots. ( I know some kids react poorly and I'm worried)

At first I thought it was a stomach bug, but it wasn't going away and I am at a loss for another explanation. No one else in the house or family who has seen her recently has had any symptoms at all.

I'm not an antivaxxer, but I'm terrified it's all related.

Has anyone had a child react like this to vaccinations?
