Additional information: The patient received Pfizer's COVID-19 vaccine for each of the injections made available to the American public. The first injection, and each of the following, thereafter affected sense of smell. The patient stated that if this continued, he would never smell again. This was frustrating for him as most foods have no flavor except for the taste on his tongue. The pleasure of eating a good meal was 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 was a little better than it was initially after he got the thing. He could not identify any smells and could 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 remembered it was after the 2nd dose 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 tasted 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. Stated when they see doctor on 29th this month and would talk to him about this again. The patient would ask once again for recommendation or referral to ENT. He read they can help people that lost smell or taste. Doctor always says of course said that was what they say. There was 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 stated the best he could do was say it doesn't taste bad.
