The reporter is the patient.  A 73-year-old female patient received BNT162b2 (BNT162B2), on 05Apr2021 as dose 2, single (Lot number: EL9267) at the age of 72 years for covid-19 immunisation. The patient's relevant medical history included: "COPD" (unspecified if ongoing), notes: she has COPD for 3 years now; "Sjogren's syndrome" (unspecified if ongoing), notes: Sjogren's syndrome Diagnosed at least 30 years ago. It means you have dry eyes and dry mouth. Body is drying out; "Thyroidectomy", start date: 2014 (unspecified if ongoing), notes: small pituitary tumor Diagnosed 4-5 years ago; "mild covid", start date: Nov2020 (unspecified if ongoing), notes: I had mild covid. The patient's concomitant medications were not reported. Vaccination history included: BNT162b2 (Dose 1, Lot Number: EN6203, Location: Arm, Time: In the morning), administration date: 15Mar2021, when the patient was 73-year-old, for COVID-19 Immunization, reaction(s): "No adverse reaction". The following information was reported: DEAFNESS (medically significant), outcome "unknown", described as "lost 80% of hearing"; ANOSMIA (non-serious), AGEUSIA (non-serious), outcome "unknown" and all described as "my smell and taste is growing worse"; WEIGHT DECREASED (non-serious), outcome "unknown", described as "lost 20 lbs"; TASTE DISORDER (non-serious), outcome "unknown", described as "fact some things taste like vomit or worse"; APHASIA (non-serious), outcome "unknown", described as "the decline in cognitive ability as far as finding my words and having the ability to express myself"; DECREASED APPETITE (non-serious), outcome "unknown", described as "she has lost appetite"; LUNG DISORDER (non-serious), outcome "unknown", described as "feels like it also affecting her lungs".The patient underwent the following laboratory tests and procedures: Acoustic stimulation tests: Unknown Result.  Clinical course: She had mild covid Nov2020. She had pfizer vaccine Mar2021 and had no initial adverse reaction. Since then she lost 80% of hearing, her smell and taste was growing worse. she has lost 20 lbs because she do not have an appetite and can not enjoy things she used to like, in fact some things taste like vomit or worse. But, the biggest concern she have was the decline in cognitive ability as far as finding my words and having the ability to express herself. She would like feedback. Consumer confirmed her the AE details indicated on her inquiry and added that she also barely has voice. Last year her doctor had her go to voice lessons for a lady that helped her do exercises and it helped her initially but then the condition came back. Caller also mentioned that her cognitive ability was getting worse, it was hard for her to carry on a conversation, if it went for more than 10 minutes, she has a hard time talking. Consumer also stated that she feels like her lungs are also affected not just the voice. Consumer also stated that she has COPD for 3 years now and also have autoimmune disorders. Caller was also aware that the smell and taste change is a side effect of covid. Caller already got 2 shots of the Pfizer BionTech Covid-19 Vaccine and her doctor does not suggest for her to take the booster shot. There were no other notable patterns or numerical imbalances (aside from appendicitis and Bell's palsy) between treatment groups for specific categories of serious adverse events (including neurologic, neuro-inflammatory, and thrombotic events) that would suggest a causal relationship to Pfizer-BioNTech COVID-19 Vaccine. Was already wearing hearing aids. Lost 80% more after vaccination. Had a hearing test summer of 2020. Had a hearing test after she had Covid. Cannot remember if it was after the vaccination or before. She remembers having a second hearing test done because around holiday and over the holidays of 2020 she was visiting and all of a sudden she could tell she lost her hearing. In her opinion, the hearing loss was caused from Covid and not the vaccine. Outcome was not getting better. Between the same and worse. Hard to tell. Smell and taste got worse: Issues with the smell and taste happened after Covid. Everything smelled and tasted nasty. At first, she had lost the taste and smell, but then it starting coming back. But, everything was tasting and smelling bad. It was bad that it was tasting and smelling that way, but at least the sense of taste and smell were coming back. After the vaccine, smell and taste starting going away again. The smell is really bad. If she closes her eyes and someone puts cinnamon or cloves in front of her nose, she couldn't tell you what it was. The taste was god awful. She loves licorice, but now it tastes horrible. Outcome: Seems like it will start getting better, then it goes bad again. It never gets good, but some days it seems like it gets better, but that does not last longer than a day. Then it was back bad. Even if she feels hungry, she doesn't feel like eating. Used to love food, and cooking, and baking, but now that is gone. Started to notice it around the holidays of 2021. Doctor said that 90% of what she is experiencing is due to the vaccine and due to timing caller would agree with that. Concerned with ability to find words and express herself. Presents as Alzheimer's, but doctor said that it is not Alzheimer's. Ability to hold an intelligent conversation is beyond her. It was a way worse in a crowd not only because of the hearing and increased conversations, but she can't keep up with any of the conversations. Her ability to communicate has decreased. It was hard to put into words what she is experiencing. Start within the last 3-4 months. Has always been a positive person, but lately she seems to have lost control of emotions, feelings, verbal reactions. She says things she would never have dreamed of saying the past. Went to see a speech and language pathologists and had sessions with her. One of those sessions was 7Sep2021, so it probably started in Aug2021. Went to her for a few sessions, and they graduated her from the program. She started to improve, but then it got worse. It seems to take energy to be able to speak. She is having to really call upon her energy reserve to be able to speak. If she had laryngitis it would be just a voice thing, but with this it seems to include her lungs as well. She wears oxygen at night and she checks her oxygen during the day and it has been okay. Oxygen is staying up for the most part. It is very frustrating. Wears oxygen at night for COPD. When she went to get the first vaccine before the March2021 date, she was just getting over bronchitis. She was still coughing and not feeling well, so they would not give her the injection then and they waited a couple weeks. Caller's sister got her vaccine first and someone called her and she made an appointment and did not question it. Her youngest sister lives in state, and her husband was in his early 70s and diabetic and he died from covid. His mother also died from covid the same day. That was before the vaccination was available and the scared of that convinced the rest of them to get his vaccine. His wife never got the vaccine. His wife had Covid, so she had natural immunity. At the time and still, the government is not recognizing natural immunity. If they had been the caller would have thought twice before she got vaccine. Vaccination Facility Type were vaccine clinic-walk in extension from Family Care. Set up in another building and did vaccines there. Vaccine was not administered at private Facility. Additional Vaccines Administered on Same Date of the Pfizer Suspect, there were no list all vaccines administered on same date with the Pfizer vaccine considered as suspect. The patient had no immediate adverse reactions. There were no any AE(s) require a visit to emergency Room but visited Physician Office, caller followed up with primary care and speech pathologist regarding AEs listed. There were no any prior Vaccinations (within 4 weeks) and list any other vaccinations within four weeks prior to the first administration date of the suspect vaccine(s) would have gotten her flu vaccine in the winter. No AE(s) following prior vaccinations. No family Medical History Relevant to AE(s). Relevant Tests: Hearing test done and was seen by speech pathologist. Would do anything to help Pfizer that might in turn help her. Has no energy, and she is so lazy. She thinks it has a lot to do with whatever is going on in her body.
