loss of taste; loss of  smell; She had full sickness for an entire week; Water even tasted like minerals; sore throat and then it started going into her lungs; malaise; diarrhea; swollen glands in neck and tongue; This is a spontaneous report received from a contactable consumer (patient). A 73-years-old female patient received first dose of bnt162b2 (PFIZER-BIONTECH COVID-19 VACCINE, Formulation: Solution for injection, Batch/Lot number, NDC number were not reported) via an unspecified route of administration on an unspecified date in 2021 (at the age of 73-years-old) as dose 1, single for covid-19 immunisation. Medical history includes that she had covid-19, 17 months ago in December/January, more than a year ago. She was one of the first people to have it. Nobody knew what it was. She stayed home and was extremely sick. She had it in her lungs so bad, she lived alone, and could not call for help. She could not manage more than a whisper. She could not get air across her voice box. She toughed it out and used her homeopathic remedies. It got better little by little and she got over it. In March, when she found out what it was. She lost her taste and smell and could not eat and got diarrhoea for 3 days and then she was flying home after the holiday beginning in January and started feeling a sore throat and then got her lungs. She got lungs so bad that after that was getting better, she was coughing so hard to get it out of her lungs. Her symptoms were the same as what she heard about in March. She did not go to the doctor. She should have gone to the hospital, and she would have gotten a ventilator and would have died. Six months later, she had a serum antibody test done to see if she had it because her doctor did not believe her, and he said to take a test and it was negative. No discernible amount could be seen in antibodies, but the test also said that antibodies could be hiding in her body if she had it and her doctor did not believe her because it was negative. The patient concomitant medications were not reported. She had her first Pfizer covid vaccine two and half weeks ago. On an unspecified date in 2021, the patient had full sickness for an entire week. She thought she still had antibodies in her and that was what she was reacting with. It was not as bad as how it was the first time. It so happened the shot was on Thursday, and she did not feel well on Saturday. There was a delay. Thursday into Saturday, two days later, food tasted funny. She thought what is wrong with food. Water even tasted like minerals. And then the next day, she had diarrhoea. The third day, she had a sore throat and then it started going into her lungs. She was using her homeopathic stuff and she stopped it dead and did not get pneumonia. She had malaise, she was sick, but it was not severe. It was a very similar reaction. About two days after Pfizer vaccine, she had loss of taste, smell, diarrhoea, swollen glands in neck and tongue then the symptoms stopped before going to lungs due to her taking homeopathic remedies, symptoms lasted 4-5 days. She thought what she needs to know is what is in the first vaccine that makes the second one different from the first. Normally, the first shot sets people up for a reaction after the second shot. She stated that this should be expected after the second shot. She wanted to know if it is different if she had Covid before. Her concern was does she need the second shot if she already had the immune boost that happens. She was schedule for the second dose. The patient underwent lab tests and procedures which included antibody test and result was negative on an unspecified date. The outcome of the events loss of taste, loss of smell, diarrhoea, lymphadenopathy was recovered in 2021 and for all other events was unknown.  No follow-up attempts are needed; information about lot/batch number cannot be obtained. No further information expected.
