Medical history included diabetes and she was a heart patient. She reported that a nurse hit a vein in her arm while giving her flu vaccine 4 or 5 years ago and had to take medicine so that the swelling in her arm would go down. The people had come to her residence to administer the flu vaccine. She had been getting the flu vaccine all her life. Either her doctor or the pharmacy gives her the flu vaccine. There were no additional vaccines administered on same date with the Pfizer vaccine that were considered as suspect. The patient did not receive any other vaccines within 4 weeks prior to the COVID vaccine. She was taking unknown medicines from a long time.The patient previously received first dose of bnt162b2 ((PFIZER-BIONTECH COVID-19 VACCINE, solution for injection),via an unspecified route of administration, administered in Arm Right on 06May2021 (Batch/Lot Number: EP7534; expiry date: 31Jul2021) as dose 1, single for covid-19 immunization. On 02Jun2021, the patient received her second Covid 19 vaccine, she was ok for 10 to 15 minutes after she received the vaccine. On 05Jun2021 she was doing some light cleaning like sweeping and vacuuming and cleaning her bathroom and she broke out profusely with sweat. She reported she sweats anyway. She got through cleaning and took a shower, and she was fine. Later her cousin came to get her for a visit and at her cousin's house she was laying on his bed and she and her cousin were talking, all of a sudden, she got real dizzy headed, nauseated real bad and she had to sit up on the side of the bed because she felt like she was going to faint on 05Jun2021. She started sweating really bad and her cousin asked her what was wrong, and she said she was not feeling good. She did not have any chest pains. Her cousin walked her into the living room where her other cousin was. The other cousin deals with medicine and stuff because she was a heart patient and had diabetes so that cousin gave her two 325mg Aspirin and some water. About 30-45 minutes later she calmed down and had put a cold bottle of water on her wrist and she had stopped sweating. She was really scared. On 06Jun2021, she woke up and had some slight sweating so she took two more 325mg Aspirin and she and her cousins went to church. She was ok for the rest of the day. Maybe on 09Jun2021 she had an episode of being sweaty a little big but not much. On that day she calmed down, drank some water and sat on the couch. Her cousins took her home on 12Jun2021 and that afternoon she was wearing shorts and a tee shirt, and she had 3 different hot flashes with sweating a little bit and she wiped off her forehead and put the fan on herself. She also had shortness of breath, was nauseated, faintness, and profusely sweating. She reported that before taking shower she had to sit down to cool off for an hour because she does sweat really easily. The adverse event not resulted emergency room and physician office visit. She made an appointment with her doctor on 18Jun2021 to get checked out. Her doctor told her she could have had a mini heart attack on 05Jun2021.

There were no relevant tests reported. The outcome of all the events was unknown.  Information on Lot/Batch number was available. Additional information has been requested.
