hair loss; This is a spontaneous report received from a contactable reporter(s) (Consumer or other non HCP) from medical information team.  A female patient received BNT162b2, BNT162b2 omi ba.4-5 (BNT162B2, BNT162B2 OMI BA.4-5), as dose number unknown, single (Batch/Lot number: unknown) for covid-19 immunisation. The patient's relevant medical history and concomitant medications were not reported. The following information was reported: ALOPECIA (non-serious), outcome "unknown", described as "hair loss".  Additional information: This report is not related to a study or programme. Caller, female, called back in Aug2021, after receiving her second dose of the Pfizer BioNTech Covid 19 vaccine, she experienced significant hair loss. There was not much information on hair loss and the vaccine at that time. She had her first dose of the Pfizer BioNTech Covid 19 vaccine on 08Jun2021, and she just had minor effects. She received the second dose on 29Jun2021, the lot number: EP7533. Within about a week, (7-10 days) she noticed she lost like half of her hair. When she put it in a bun it used to be the size of a tennis ball size and now its just the size of a ping pong ball. It was quite noticeable, perhaps it started after second dose, reached to put hair up and she reached up and she said where is her hair? Perhaps it started after the first dose, but she did not notice until after the second dose. It was quite noticeable. When she first started researching it online really only saw people who had actually had Covid might have had hair loss but there was nothing about the vaccination. Then she kept looking and she told her doctor, her nurse, her dermatologist, and they could not think of anything else. They did a bunch of blood tests. She called Pfizer in Aug2021 to report side effects, and the person said they had not heard of anyone else having that side effect. Now that we have gone almost two years later, she has seen other reports of other people having this effect. She has a nurse that she sees weekly. Her nurse's daughter moved to (place name withheld) and was doing a haircut for (name withheld) son. She has the same issue as her but not quite as severe as her. Somehow, they got to talking about it (name withheld) son told her that it had become a problem and that Pfizer was potentially offering some type of compensation because its horrible. She is not being vain, but she used to have really nice hair and now it looks horrible. And there is barely any of it. Its fine in the winter when she can put a beanie on but now she is embarrassed to go out in public. Its been miserable. She cannot be the only one now. Its not an injury per se but it is a big side effect and its affected her life. There is no other explanation, nothing else changed with medical issues, prescription issues, only thing that happened that month. Her doctor told her not to get any other boosters because it could make it worse, so she only had the first two doses. She is calling back now to see if there is any additional information about hair loss after the Pfizer BioNTech Covid 19 vaccine (For dosage/dosage form, "Not Specified/General" was selected because although there was only the monovalent formulation of the vaccine, which type it was unknown. Lot for second vaccine received: EP7533. Is there any additional information about hair loss after the Pfizer BioNTech Covid 19 vaccine. Question: Do you know of anything Pfizer is starting to do a compensation program due to hair loss from the vaccine? Is there some type of compensation program? Is it through the government or through Pfizer? Is it like a federal thing where its any brand? How does she submit a claim, is there a form to fill out or anything? She is surprised there is no other info if this person heard it from a government official. Maybe she will just wait a little longer and see if something becomes more public.
