She has a lot of drug and other allergies, the only that was anaphylaxis was bees and egg. This was why she brought 2 EpiPens when she had the shot. She didn't have to use her EpiPen and was really proud of that but did have some reactions.  The patient reported she did not go to the doctor. At this point she was somewhat expected that she had a not great reaction so the fact that she could still breath after getting it was a good thing.
