Symptom narrative

Patient was given MMR first on the left arm, then Hep B immediately after on the right arm. About 2 minutes later, patient reported feeling dizzy, then suddenly lost consciousness (head dropped as if she fell asleep and sounded as if she was snoring). She was unresponsive for about 30 seconds, then suddenly regained consciousness. She seemed alert and said she felt fine and unaware she had passed out. She said she still was a little dizzy and was starting to feel nauseated, then lost consciousness again for about 20 seconds, again sounded like she was snoring and also made a gagging sound shortly after she regained consciousness. Mom was called and suggested she stay for a while and be observed. Patient said vision was a little blurry and skin was a little cold, but symptoms were slowing improving. Observed for an hour, while mom was trying to figure out what to do. Patient remained alert and oriented and patient claimed symptoms had resolved after about 20 minutes post-vaccinations. Blood pressure readings were taken, patient was given water and feet were elevated.
