intense gastric/stomach pain; pain still persisted; intense abdominal cramping, which was around, either right below the stomach, or right around that large intestine; Sore left arm; discomfort for two days that went up into her chest a little bit, but the predominant gastro location; This is a spontaneous report from a contactable consumer (patient). A 35-year-old female patient received bnt162b2 (PFIZER-BIONTECH COVID-19 VACCINE, solution for injection, lot number was EW01a8 and expiration date was not reported), dose 1 via an unspecified route of administration, administered in arm left on 01Jul2021 at 21:50 (at the age of 35-year-old) as dose 1, 0.3 ml single for COVID-19 immunisation. Medical history included small heart, and pains on the left side of her chest prior to vaccination. She stated that she did not know if it was a condition, she just found out recently she has a small heart, but she was a pretty petite girl, and did not know if that was normal for her. Family history included she had an immunocompromised parent who received the Pfizer BioNtech Covid-19 Vaccine and her dad had a heart attack after Moderna vaccination. She stated she didn't really want to comment too much because she did think he had pre-existing conditions, they did not have a great relationship so she really could not give a lot of information on him, she couldn't even tell his favorite color. The patient's concomitant medications were not reported. The patient previously took Panmist and experienced reaction to Panmist. She stated that Panmist sent her central nervous system out of whack, and added, compared the ingredients and it was said that nothing was in the Pfizer vaccination that was in Panmist. She stated that it occurred around the age of 12 years, and form or how medication was taken was unknown. On 01Jul2021, the patient experienced intense gastric/stomach pain, pain still persisted, intense abdominal cramping, which was around, either right below the stomach, or right around that large intestine, sore left arm, discomfort for two days that went up into her chest a little bit, but the predominant gastro location. Clinical course: The patient stated that she received the first dose of the Pfizer BioNTech covid-19 Vaccine on 01Jul2021 and experienced intense gastric pain for about 20 minutes and subsided. The pain still persisted for about 2 days. She also experienced abdominal cramping for about 2-3 days. The patient stated that she got her first shot 01Jul2021, which was really exciting, but about twenty minutes after she got her shot, she started having really intense gastro pains, and it did not come out either end, it was not vomiting or diarrhea, it was just pain. She added that lasted a few minutes, then for about two days, it wasn't acid reflux, but it was that whole kind of feeling for two days. She did not have a history of acid reflux, she was 35, pretty good so far, on a lot of boxes, she wa pretty healthy. Her question really was regarding that pre-covid checklist, on page six of the pre-vaccination checklist, it said if you have any gastrointestinal reactions, that you shouldn't get the second shot. She asked, was that true. She stated, if this sounds familiar at all, she did not know if it would give her peace of mind that it's not necessarily uncommon, because she hadn't really heard anyone having this that she knew. She got the shot from pharmacy around 21:40 or 21:50, she tried to go at a minimal time, she cared for a immunocompromised individual, so she needed the most minimal traffic as possible. She clarified the symptoms occurred before 22:30. There was a real discomfort for two days around that same area, that almost went up into her chest a little bit, but the predominant gastro location. She confirmed after forty-eight hours, it did completely resolve. She had the sore arm, which was fine, she's just more concerned about that gastro cramping, and why it said not to get the second shot, she just wants to know, she did not want to screw up. It was her left arm, and it occurred later that same night, but she immediately started wrapping it with cold rags and exercising it, and she did not experience a big issue with that, due to the proactive measures she was taking to try to heal the muscle. She stated by the full second day, she was doing well compared to a lot of people, and she confirmed the sore arm had resolved by 03Jul2021. Caller confirms the gastro pain was fully resolved by Sunday, 04Jul2021, it was all relieved, it was all ok, she was on alert. She confirmed the time of vaccination as 21:50. She was pretty healthy overall and was not on any medications and still was not, she didn't even take ibuprofen or anything like that for her arm, she just wrapped it and exercised it. She stated that she had been having pains on the left side of her chest prior to vaccination, but she thought it's stress induced, because her x-ray looked okay. She thought it's just from the isolation and extreme measures. Investigations: she stated no, but added, the weekend prior to her getting the shot, she ended up in urgent care for her mom, and caller got looked at for her chest, and they referred her to a cardiologist, but her tests were scheduled for this week, so Tuesday of this week, 06Jul2021, she had blood work and they did an x-ray. She clarified this was for the previous chest pain that she had prior to getting vaccinated and not for the symptoms reported after the vaccine. She confirmed it was a chest x-ray, and states everything looked fine. She added, there was a number she needed to ask the doctor about, that was low, but she didn't understand it. She stated she did not know what lab was low, she would have to pull it up. She stated she would hate for this to be correlated with the vaccination, when there was no science to it whether it was related to that experience or not. The outcome of the event sore left arm was resolved on 03Jul2021 and other events were resolved on 04Jul2021.  Follow-up attempts are completed. No further information is expected.
