HCP mentioned that this is her first patient who has a severe allergic reaction to the Pfizer vaccine. She was feeling better. She was told to call her doctor about getting the second shot.

She knows she is not supposed to have raw tomatoes. A couple of days ago she had a dressing that must have had raw tomatoes in it because she had throat swelling. The patient said what happened with Pfizer was more. She knew it when it was happening because it has happened before. She had no hypoxia. The patient reported that her pulse ox was checked and was in the high 90's. The patient was able to swallow. No drooling. She did have nausea and sweats. It was six out of ten in the ER.
