Clinical narrative: severe allergic reaction; Experienced elevated heart rate  while driving; Dizziness; Weakness; This is a spontaneous report from a contactable consumer. This 41-years-old female consumer reported (patient) that she received first dose of BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE, Batch/lot number: EW0169) at single dose on 16Apr2021 2:30 P.M for COVID-19 immunisation. Relevant history and concomitant drug was unknown. The patient did not have additional vaccines administered on Same day. The patient had not have prior vaccinations within 4 weeks.  The patient had experienced elevated heart rate/ fast heart beat while driving, within an hour of getting the vaccine. However she mentioned that when she went home, she just relaxed and it eventually went away. But 12 hours after, she experienced the same elevated heart rate side effect and she just sat down and it went away. This happened again after 24 hours. She also mentioned that she had experienced dizziness coupled with weakness. She did not have any side effects or issues until her heart rate started increasing after she left the vaccination site. She read the papers and saw that technically a fast heart beat was considered a severe allergic reaction. She did not notice it was listed at first, because all of the severe allergic reactions blended in together for her. She was wondering when she can expect her heart racing to go away. It had been coming and going. She had experienced it three times now. She did not realize that it was technically a severe allergic reaction. She thought that it was just a side effect, and that it was normal to happen. After receiving the covid vaccine, she waited at facility for 30 minutes afterwards. She was advised to wait because she was allergic to strange things. She did not have any reaction while she waited. Her heart started beating fast on her drive home, within an hour of receiving the covid vaccine. She received the covid vaccine at 2:30PM. Her heart rate rapidly increased again on Saturday morning, probably about 12 hours after receiving the covid vaccine. The third time it happened was within 24 hours after that. She was not overexerting herself. She was working in her yard. She works out 5-6 days a week, but she has never experienced her heart beating fast like this before. The second time it happened was on 17Apr2021, about 8:00AM, and it caused her to stop what she was doing, and sit down. She was unsure whether it was improving or persisting, but she definitely knew it had not worsened. She was second guessing herself about choosing to get the covid vaccine. She never had covid. Her worked offered the vaccine to her. She thought it would be a seamless transaction. She was a healthy individual. In the past, she has been closely exposed to people that had covid, and she never caught covid.  She was concerned that her fast heart rate may be long term. If because of the covid vaccine, she has a heart thing now, she will be devastated. Outcome of the event was unknown. The patient did not require a visit to emergency room or physician office. She thought it might be relevant that she donated blood earlier in the day.     No follow-up attempts are possible; information about lot/batch number cannot be obtained.
