My daughter received the mmr vaccine just over a week ago. About 2 days ago, I noticed a rash above her lip and now today it has spread really bad. She also has a high fever (103), diarrhea, she's lethargic, and she won't eat anything. I'm pretty sure she's having a "mild case of measles" from the vaccine, which I read is pretty common. She has a doctors appointment in the morning, but I feel really worried like I should go ahead and take her in. Has this happened to anyone else??
