hearing loss has become worse; hearing loss has become worse; tinnitus/Then she recieved the booster and it exacerbated it worst; This is a spontaneous report received from a contactable reporter(s) (Consumer or other non HCP) from medical information team. The reporter is the patient.  A 54-year-old female patient received BNT162b2 (BNT162B2), on 11Oct2021 as dose 3 (booster), single (Lot number: 301308A) at the age of 54 years for covid-19 immunisation. The patient's relevant medical history and concomitant medications were not reported. Vaccination history included: BNT162b2 (Dose 2,Single, lot ER8272 , expiry date 21Jul2021), administration date: 29Mar2021, for Covid-19 immunization, reaction(s): "she developed severe tinnitus"; BNT162b2 (Dose 1, Single, lot EN6208 , expiry date 21Jun2021), administration date: 10Mar2021, for Covid-19 immunization; Bnt162b2 (Dose 2, Single, lot ER8272 , expiry date 21Jul2021), for Covid-19 immunization, reaction(s): "Hearing loss", "Hard to sleep". The following information was reported: DEAFNESS (medically significant), CONDITION AGGRAVATED (non-serious) all with onset Oct2021, outcome "not recovered" and all described as "hearing loss has become worse"; TINNITUS (non-serious) with onset Oct2021, outcome "not recovered", described as "tinnitus/Then she recieved the booster and it exacerbated it worst".  Clinical course: The patient received the first three doses of the Pfizer Covid 19 Vaccine. Patient was unsure of the color vaccine. After the second vaccine her prior diagnosis of tinnitus became worse and caused some hearing loss. Reportedly, after about six months the tinnitus seemed to go back to how it was originally. Then patient received the booster and it exacerbated it worst and that was back in October. It has not gotten better and the hearing loss had become worse. As per reporter the patient was over due for her fourth shot at age 54 years old with other health issues and reporter informed patient just don't know what to do. Patient was waiting to saw if it would went away and it hadn't. Patient fear was if she gets another one might going to make it even worse to the point that patient becomes debilitating from the tinnitus and hearing loss. Reporter mentioned patient had a bad reaction to the Pfizer Covid19 vaccine and wanted to figure out how patient can safely get the booster shot. Reporter verified the information provided by the transferring agent and stated patient had three shots so far all were the Pfizer Covid19 vaccine and after the 2nd shot patient developed severe tinnitus then clarified patient had already had tinnitus but it was exacerbated; it seems to have caused some hearing loss and over the next 6 months seemed to have diminished. Then patient got the booster last Oct and the tinnitus got extremely exacerbated and the hearing loss is pretty severe in one ear now so patient should be getting the 4th shot but just does not know what to do and was terrified this will get worse; consider this did not get better after the 3rd shot and she does not see how or what she can do. Third dose administered on 11Oct2021 and lot is handwritten and she thinks it is 301308A and the patient card did not include an expiry date for the 3rd dose or any NDC numbers.  No follow-up attempts are possible. No further information is expected.
