Clinical narrative: lost complete hearing in one ear/ sudden loss of complete hearing in her left ear/ lost hearing in left ear/ hearing loss in left ear; This is a spontaneous report received from contactable reporter(s) (Consumer or other non HCP) from medical information team for a Pfizer sponsored program (003110). The reporter is the patient.  A 74 year-old female patient received bnt162b2 (PFIZER-BIONTECH COVID-19 VACCINE), administered in arm left, administration date 22Feb2021 11:15am (Lot number: EL9267) at the age of 74 years as dose 2, single for Covid-19 immunisation at a hospital because they were saying she should get it because of her age. Relevant medical history included: "Cholesterol" (unspecified if ongoing); "hearing aids" (unspecified if ongoing), notes: prior to receiving the vaccines. Family history included: "Mom had hearing issues when she was in her 90's" (unspecified if ongoing). The patient had no other conditions. Concomitant medication(s) included: SIMVASTATIN taken for cholesterol. Vaccination history included: Bnt162b2 (Dose 1, Lot: EL9261, Expiry: Unknown, NDC: Unknown, Dosage text: Unknown dose by injection in left arm), administration date: 01Feb2021, when the patient was 74 years old, for Covid-19 immunization, reaction(s): "No adverse effect". No additional or prior vaccinations (within 4 weeks) was given. The following information was reported: SUDDEN HEARING LOSS (medically significant) with onset 2021, outcome "not recovered", described as "lost complete hearing in one ear/ sudden loss of complete hearing in her left ear/ lost hearing in left ear/ hearing loss in left ear". The event "lost complete hearing in one ear/ sudden loss of complete hearing in her left ear/ lost hearing in left ear/ hearing loss in left ear" was evaluated at the physician office visit. It did not require emergency room visit. The patient underwent the following laboratory tests and procedures: hearing test: (Mar2021) no hearing in left ear. Therapeutic measures were taken as a result of sudden hearing loss. Additional information: After receiving the second Pfizer COVID injection (2nd dose in Feb2021), the patient lost complete hearing in one ear (her left ear). She didn't know the specific date of when she completely lost the hearing in her left ear, but it was sometime in the first week after the 2nd shot, which she received on 22Feb2021. She had hearing aids prior to receiving the vaccines. She would hear "battery low" with the hearing aids. The hearing aids generally beep to tell her when the battery was low, and she was having problems with the left one but it never told her that the battery was low, so she took it out and covered her right ear and she noticed that she couldn't hear anything at all from her left ear. The right one kept going off but the left wasn't and that's when she consulted her ENT. She called the ENT and saw him on 29Mar2021 or 30Mar2021; they did a hearing test that day (on 29Mar2021 or 30Mar2021) which showed she had no hearing at all in her left ear; they called it sudden deafness. She did see her ENT who gave (prescribed) her prednisone and antiviral antibiotic medication (didn't remember the name) to see if it would come back, it didn't (her hearing did not come back). Her ENT said there's nothing wrong with her hearing aids and that she had experienced sudden loss of complete hearing in her left ear which was strange. She had a return visit to the ENT 2 weeks later to see if anything had changed and nothing did, so she saw the audiologist who suggested hearing aids that pick up sound in the left ear, but the speaker was in the hearing aid in the right ear. So she was learning to live with hearing in one ear with the help of new hearing aids to help. Just wondering if Pfizer had other such side effects reported. It's been driving her crazy so she thought she would call to see if there was any information about it. Her ENT said that they couldn't prove that her hearing loss had anything to do with the vaccine and he hadn't read anything about it. She also mentioned she has taken the booster shot on November with the go signal from her ENT. Before she got her booster dose, she called and asked the ENT if she should get the booster, and he said that it was okay to get it; she didn't have a problem with the booster dose, but she told the nurse that gave her the booster about what happened. Pfizer Covid 19 Vaccine 3rd dose (booster) received on 22Nov2021 (Lot number: FD0809). She said so far it was pretty good.
