Additional Information: Consumer stated, "I have a question to ask you. I am going to make this really quick, and I thank you very much for taking my call. This is my question, I had two of the Pfizer vaccines (Pfizer Covid-19 Vaccine) both in March, one in 21Mar and 28Mar2021 and then I went home. And it started from a pain in my arm and a little bit of fatigue. I feel this has gone pretty well. I go for the Covid-19 Booster on 18Nov2021 as I am 'leading' the facility that is called (hospital name) in (City name), (State name) and my arm is really hurting. About a week or two later I started to notice that I am hearing a hissing sound in my ears which has remained with me to this day. I am beginning and doing some research that there have been some cases of tinnitus, onset of tinnitus, onset of tinnitus that patients (not clarified) have noticed after taking the Pfizer Vaccine and I have read some literature that there is a compared Pfizer to Moderna to J&J. It looks like there is a small percentage and it is rare. It does appear that Pfizer has the most of them and I would like to find out the information that you have got." Consumer stated, "Now let me explain to you I am working right now. So, but I just wanted to get, I would try to make this is efficient as possible and if there is anything that you can send me, email me. I would appreciate it because I was scheduled to go for the second vaccine, the booster, on Friday and I am refraining from doing because I do not want it to create more problems with tinnitus now that I never had before. Mainly I had the occasional ringing. I did not have a medical history of tinnitus and now I have, you know I am tinnitus patient now." Consumer stated, "The booster that you get after two vaccines. Whatever it is called. Hold on one second. I mean I just went for the vaccine. They did not tell me what exactly it is called? But I took the first vaccine on the (incomplete sentence). It is Pfizer FH8028 (not clarified) whatever that means and then it says it says 18Nov2021. So, there was first two Vaccines. It is the Covid-19 Vaccine. The way this rolled out and I do not want to be rude. Two of them were done through North Well one was done through (hospital name). I think it is the Covid 'company name' Centre and the third one, the first two were the Covid-19. First dose, second dose and the other were Pfizer which would have been the booster that done after the second dose. So, what is that called."
