Additional information: The patient received Pfizer's COVID-19 vaccine for each of the injections made available to the public. The first injection, and each of the following, thereafter affected sense of smell. The patient states that if this continues, he will never smell again. This is frustrating for him as most foods have no flavor except for the taste on his tongue. The pleasure of eating a good meal is lost. Every vaccine he has received, he has a loss of smell and gets a little better and gets next dose or booster vaccine and loses sense of smell again. Just got latest Pfizer Covid vaccine and it happened again. loss of smell - is a little better than it was initially after he got the thing. He cannot identify any smells and can tell difference between some foods but not what they are; it makes a big difference on what he enjoys. The first time noticed the loss of smell was after the first two initial vaccinations he got a month apart. He remembers it was after the 2nd dose is when he realized what was going on. It has stayed about the same, it got a little better and when he got the next booster shot it went back. That happens each time he gets booster shot. He doesn't know how to explain improvement, he can tell a little difference between fruit or maple syrup but not the flavors for example. If he has a hot cup coffee in front of him, he can't smell it. But it tastes different, something there but doesn't know what it is. Mentioned to primary care doctor and see him end of this month (Nov2023) and will mention again. States when they see doctor on 29th this month and will talk to him about this again. Going to ask once again for recommendation or referral to ENT. She read they can help people that lost smell or taste. Doctor always says of course said that is what they say. She is going to insist. There is nothing more heart breaking for someone that can't smell and forget and say this smelled really good and hope it tastes as good and you are the only one able to taste and smell it. Caller states the best he can do is say it doesn't taste bad.; Sender's Comments: Linked Report(s) : US-PFIZER INC-202300367705 same patient/drug/event, different doses;
