This is a spontaneous report from a Pfizer-sponsored program. A contactable consumer (patient) reported that a 75-year-old female patient received BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE, solution for injection, lot and expiry were not reported), via an unspecified route of administration on 07May2021 (at the age of 75-years-old) as 1 st dose, single for COVID-19 immunization. Medical history included feeling jittery (started before she got the COVID-19 vaccine); nervousness (started before she got the COVID-19 vaccine); stomach was hurting (feeling like her stomach was hurting all the time); anxiety (had for years/started before she got the COVID-19 vaccine); bowel obstruction in 1990; bowel syndrome; polypectomy (removed a polyp and she hasn't had any problem since then) on 26Mar2021; colon problems (has valve syndrome and suffers with that/started before she got the COVID-19 vaccine); thyroid that is kind of slow (hands tremble sometimes because of her thyroid that is kind of slow); trembling (for at least 2 years/started before she got the COVID-19 vaccine) and stomach problems (had for years/started before she got the COVID-19 vaccine). Concomitant medications was unspecified (took her regular medicine) and has all different medicine. The patient called to get information when she needed to come back. The patient was asked if she received the vaccination card, said that she did not receive it but there was a paper given for the date which was 28 May for the second dose, however there was no time indicated. The patient mentioned that she was disoriented (in May 2021) after receiving the first dose and she lost the vaccination card. On 12May2021, the patient stated that the report was not related to a study or program. In May 2021, the patient reported that she has been feeling better with her regular health problems after she got the shot. The patient just got the first dose of BNT162B2. She was there by herself and was just wondering what she should do. She took her regular medicine. She had the shot last Friday. So far she has been sleeping off and on for a couple days (in May 2021) and resting pretty well. She didn't know what to do if she should go in or just take her regular medicine as she has been doing. She will give her regular medicine time to work. She couldn't make her mind up on what to do. She got up this morning (in May 2021) and was feeling pretty good, she was stirring around then got nervous and jittery. She went through this anxiety before even before she got the vaccine. She just took one of the pills for anxiety. She got the card to find out how this shot was supposed to work and the side effects. She didn't know how to deal with it. She was stirring around maybe too much and just took her first pill of her anxiety medicine. She has all different medicine. She was getting the second shot on 24May2021. She was sitting down but she has had those attacks before the vaccine anyway. She has degenerative bone disease and a sciatic nerve in her back that was painful (in May 2021). She gets a pain shot and has one of those coming up soon. Sometimes she trembles (in May 2021). After she takes all her medicines that ceases. She hasn't eaten anything yet and has diabetes too (in May 2021). She was sitting still and talking to someone helps. She suffered with an inflamed ulcer too (in May 2021). The patient was very skeptical of different medicines and stuff. She has been on medications for years and looks for side effects with medicines. The outcome of the events was unknown. No follow-up attempts are possible; information about lot/batch number cannot be obtained.
