Dementia; She has no taste anymore; Pretty severe heart rate racing; This is a spontaneous report received from a contactable consumer. A 76-year-old female patient received BNT162B2 (PFIZER-BIONTECH COVID-19 mRNA VACCINE; formulation: Solution for injection, Lot Number: EL9265; Expiration Date: 31May2021), dose 1 via an unspecified route of administration in arm left on 02Feb2021 (age at vaccination was 76-year-old) as dose 1, single for covid-19 immunisation. Vaccination was given in the afternoon. Medical history was not reported. Concomitant medications included losartan potassium taking for about a year and amlodipine besilate, taking a year and a half or so, both taken for hypertension. She had a lot of vaccines and never had any reactions. She was a 77-year-old lady that got the first shot on 02Feb2021. She was looking at the vaccine and first thought that is when it expired and then said it was the date, she received it. This was only her first dose. She had pretty severe heart rate racing on 02Feb2021 at unknown time. She could not stand up and they took her to the back to lie down. She doesn't know if they reported it or not. She does not want to be forced to have another vaccine. She got it last year then clarified it was 02Feb2021. They said if she has another shot, she may have an anaphylactic reaction. She said she can't remember a damn thing anymore. She would not say it is related and has that little bit of dementia on an unspecified date, where she has to write everything down. This is just age related. On an unspecified date at unknown time, she has no taste anymore. She did not realize it at first that she was not eating and noticed in the last 5-6 months that nothing tastes good anymore. At first, she did not associate it. She read about other people that had a problem with taste and smell. There are no specific people she knows of. She just read it somewhere. She just looked at a form and said this should be reported. She does not want to have to be forced to get second dose. It was recommended because she was at risk for COVID because of her age. She takes blood pressure medication. She was on the Amlodipine Besilate and it did not lower her blood pressure, so they added the Losartan. It is in a pharmacy vial with no lot or expiration. Product strength and count size dispensed: 5mg, count not provided. There is no Packaging sealed and intact. It was in a pharmacy vial. No sample of the product available to be returned, if requested. She does not want to be short 1 pill. She would not send a tablet. It was not sealed because it is in a pharmacy vial. She was perfectly normal except her elevated blood pressure. It is not elevated anymore as long as she was taking the medication. She did not go to the doctor, but probably should have, but did not want to pay money. It looks like the government administration will force them to have another shot. She hopes nothing happens. These drugs are experimental. The patient did not visit Emergency Room and Physician Office. Outcome of the event dementia was unknown, pretty severe heart rate racing was recovering and she has no taste anymore was not recovered.  Follow-up attempts are completed. No further information is expected.
