because this had started before the most recent one and the two before that/but I've had some issues in being able to retrieve a word that in the past; 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.  An 80-year-old male patient received BNT162b2 (BNT162B2), in 2022 as dose 3 (booster), single (Batch/Lot number: unknown) for covid-19 immunisation. The patient's relevant medical history included: "sometimes have a little hearing disparity among different "deafness"" (unspecified if ongoing). The patient's concomitant medications were not reported. Vaccination history included: Bnt162b2 (Dose 1), for COVID-19 immunization; Bnt162b2 (Dose 2), for COVID-19 immunization. The following information was reported: APHASIA (non-serious), outcome "unknown", described as "because this had started before the most recent one and the two before that/but I've had some issues in being able to retrieve a word that in the past". Relevant laboratory tests and procedures are available in the appropriate section. Additional information: This case was reported as not serious. HCP contact information was not available. Product: Comirnaty, Pfizer-BioNTech COVID-19 Vaccine [Monovalent] and/or Bivalent. Dose/Dosage Form: Not Specified/General. Caller stated: "I have a lot of questions. I have nothing against the lady that transferred me, but I could not understand what she was saying, I am from (place withheld), I'm 80 years old, I sometimes have a little hearing disparity among different "deafness." Has anybody reported anything happening to their ability to be able to retrieve words from what used to be a normal brain? Until last summer I never had a problem that I questioned my own brain's ability to communicate or to think clearly. I lost my wife last summer, of 60 years, we had two of the Pfizer vaccines. After she passed away, I think on August I had another Pfizer vaccine, maybe in November or December, and then just last week, the final booster, but I've had some issues in being able to retrieve a word that in the past I would've have used extensively or just a normal communication, never wind up with a void in being able to think of a certain word. I am a retired person, they did an MR several weeks ago, with no indication of amyloid built up around neurons "unintelligible" or anything on my brain, no indication of early dementia, I am just trying to pin some sort of label on something that might have been occurring to me in the past years or so, and I was just asking the question, has anyone else ever reported anything similar to what I reported. Maybe it's just, I lost my wife last summer, some people say that is just grief, but I don't know that is just grief. " Caller added: "It might be after almost 60 years of marriage I lost my wife last summer and it's ironic, on April before I lost her we had had our second vaccine, and then in the fall I had I think two and then most recent one just a week ago, but I would not think anything, you know, the recent vaccine or that one in the fall, would be any, because this had started before the most recent one and the two before that, it's so strange, but it might be grief, because I lost my wife there's something there that's going on, it's something that I wanted to reported because it's something totally out of character of me, never existed before".  The information on the batch/lot number for BNT162b2 has been requested and will be submitted if and when received.
