Clinical narrative: stomach pain last about for 2 or 3 days, stomach pain came back after second dose; The pain was so bad he couldn't stand up.; The x-ray showed he had a big black spot in his stomach and the doctor told him it was a blood clot.; This is a spontaneous report from a contactable consumer (patient) and a physician. A 68-year-old male patient received the first dose of BNT162B2 (PFIZER COVID-19 VACCINE, lot number: EN6198) on 26Feb2021, and the second dose of BNT162B2 (lot number: EN6208) in arm on 19Mar2021 , both at the age of 68 years old at single dose for covid-19 immunisation. Medical history was none. The patient's concomitant medications were not reported. The patient previously received flu vaccine in Oct2020 or Nov2020. The patient had his first dose of BNT162B2 on 26Feb2021 and about 4 days later he had stomach pain on 02Mar2021. It lasted about 2 or 3 days then the stomach pain let up. The patient thought the stomach pain was over. Then the patient received his second dose of BNT162B2 and in about the same amount of time after receiving BNT162B2, the stomach pain came back. On Mar2021, the pain was so bad he couldn't stand up. The patient went to the doctor and he was given 4 ground up Aspirin to take. The patient screamed when the doctor pressed on one spot of his stomach. The patient was taken to the x-ray room and his stomach was x-rayed. He was asked where the pain was and when the doctor pushed on that spot, his back arched up in the air because it hurt. The x-ray showed he had a big black spot in his stomach and the doctor told him it was a blood clot. The doctor on call said it was a blood clot and his regular doctor told him it was a blood clot. The doctor's determined the blood clot was from BNT162B2 because the blood clot happened right after he received the vaccine. Besides his regular doctor who is listed in the formal field, he also saw another doctor when he went in that day with the stomach pain. He was told his regular doctor was busy and he had to see another doctor. The patient didn't have any blood drawn at the doctor just the x-ray of his stomach. The doctor said he had a blood clot, a black spot, about the size of a silver dollar in his stomach. The doctor clamped her index finger and thumb together in a circle to show him how big the black spot was. The x-ray technician and two doctors told him it was a blood clot. He had the 4 aspirin ground up and the doctor told him the aspirin got rid of the blood clot. He also took some pills for 2 to 3 days but he can't recall the name of the pills. He says the x-ray tech zeroed in on the spot that was causing him pain in his stomach. The outcome of events was unknown.  No follow-up attempts are needed. No further information is expected.; Sender's Comments: Considering the temporal association, a causal association between administration of BNT162B2 and the onset of blood clot cannot be fully excluded.
