I am talking about a lot of hair loss like more than a 100 hair a day; This is a spontaneous report received from a contactable reporter(s) (Nurse). The reporter is the patient.  A 68-year-old female patient received BNT162b2 (BNT162B2), on 17Feb2021 as dose 1, single (Lot number: EL9264), in left arm, on 14Mar2021 as dose 2, single (Lot number: EN6207), in left arm and on 26Sep2021 as dose 3 (booster), single (Lot number: FF2587) at the age of 67 years, in left arm for covid-19 immunisation. The patient's relevant medical history included: "Osteoporosis" (unspecified if ongoing), notes: Osteoporosis; "Thyroid" (unspecified if ongoing); "Osteo arthritis" (unspecified if ongoing). Concomitant medication(s) included: SYNTHROID. The following information was reported: ALOPECIA (non-serious), outcome "unknown", described as "I am talking about a lot of hair loss like more than a 100 hair a day". Relevant laboratory tests and procedures are available in the appropriate section.  Additional information: Patient had received 2 sets of Pfizer and one booster. Her first dose of the Pfizer vaccine was 17Feb2021, second dose was looks like 14Mar2021, she looked at her little slip here and then her booster was 26Sep2021 and she called because last year in let's see it would have been December of 2021, she started having some hair loss and had a thyroid condition so, thought it perhaps this hair loss and she was not talking about little bit of hair loss, she was talking about a lot of hair loss like more than a 100 hair a day like when she brush her hair her hair comes out a 'lot' and it seems to be, what she had noticed. reporter was nurse, retired nurse at this point. Reporter thought it was my thyroid acting up and so on 2 occasions. She had gone to my physician and have thyroid testing done because thinking that my thyroids level are low and to increase my thyroid medication but that is not the case, every time she goes and have the check my thyroid was fine so, she like trying to figure out why she was losing all this hair and it seems to be, that this hair loss seems too happened after I have had you know may be a month later, she had the covid vaccine, both the booster and because I started noticing hair loss in like a March of 2021 and then around the holiday of 2021 so, I am like (Incomplete sentence), she went to have a doctor's Ophthalmology test last week. She was talking to a girl that was checking her vision and she did not know how we got talking about this but she said that she have had a covid infection and she said that her hair has started to fall out and you know while she was having covid she was having terrible loss of hair, she was like bald headed and after she got better with covid infection she said that she went took the covid vaccine, she did not know she had Pfizer or Moderna, She did not think to ask her that but she said after she had the covid infection and then she went and had vaccinated and she said she is still having extreme hair loss after having covid infection and then having her covid vaccination after having had a covid infection. So, reporter just curious that is why she was trying to report this because she was looking online and trying to figure out if other people who had either covid infection or have had covid vaccine, was the hair loss, significant hair loss is one of the side effect. Reporter just wanted to report it because she thought that may be something that if may be she was having problem so the other have also noticed that the hair loss as a side effect. Causality was reported as she had no idea (hence checked as unknown) but it's quite a co-incidence that within a month in each case within a month of getting the Pfizer vaccine, I started having hair loss. I am just trying to report it just because I think it is an odd co incidence and I am wondering whether other people have experienced the same thing, within a month of each shot and they tell me because of my age I should get another booster because I am not going to have any other hair loss, my hair is really falling out a lot and I just have a sneaking suspicion that it might be have a side effect of getting immunity from covid may affect hair growth. I am just curious whether this may be a side effect, my hair is growing back an area where I lost hair, It is coming back. I am just curious weather this could be related to covid." Other medication was reported as "I am on Fosamax actually Alendronic (further not confirm, hence not captured in tab). Then I have started taking biotin because of the hair loss, may be if I started taking biotin that will prevent more hair loss and I don't really think that's the case because it hasn't helped but I continue to take it because my hair is falling out." Lab test was reported as "Yes, within last 2 weeks. Actually, I had blood work, 2 weeks ago and then 6 months before that because I thought my hair was falling because of my thyroid test and so the doctor checked my thyroid function and my thyroid function is perfect so you know when your thyroid function is out of way you can lose so many hair but my thyroid function is perfect so, it's not that helping the hair loss." It was reported that "I don't have the one taken last year because it's new year but the last one was 28th of April and the other test would have been done Oct2021, it was either October or November." For treatment: consumer stated, "No, I don't know what to do to stop the hair loss, maybe it's a super glue." The events were persistence. The patient did not had prior vaccinations (4 weeks). When asked permission to file a safety report for other patient: Consumer stated, "I don't, I don't even know the girl's name. We were just talking at the doctor's office and it never would have occurred to me that my hair loss could have been caused by covid, it never would have occurred to me until talking to this girl who described what did happened to her and describing her hair loss and I said, I heard of people having long covid, I heard of people having on going respiratory problems after having a covid infection but I hadn't heard of hair loss is being result after an injection or after having a covid infection. This one had a covid infection and had the hair loss. I was just curious whether anybody else has reported similar things, I don't necessarily know it was result of the shots I got, it was quite co incidence though that these things happen within of receiving these injections. You know I really didn't notice after the first shot but I really did notice after the second shot in 2021 in spring and once again then about a month after having receive the booster shot fall of the last year."  No follow-up attempts are possible. No further information is expected.
