Vaccine Adverse Event Reporting System,   I received the first Pfizer Vaccine (EH9899) on 12/19/20. A few days later, I felt like my head, on the side of my right ear, had a great deal of pressure in it and it felt "funny " but it did not really hurt. It was uncomfortable and distracting. I waited to see if it would go away. I noticed my hearing was decreased . On 01/06/20 when I woke up, my hearing was completely gone in my right ear. I could hear nothing out of that ear.  I had a noise in my head. Just a loud roaring noise. I had severe vertigo and could not walk across the room. I describe this as I felt like I was on a merry-go-round and someone was spinning me really fast. (continue)  Additional information for Item 18: Vaccine Adverse Event Reporting System,   continued:    I also experienced severe vomiting and could not stop. My husband took me to the doctor. Since I could not get in to my regular doctor that day, we went to an ear doctor I had visited a couple of years ago because that was the only person I could find to see me on short notice. I had regular hearing test in the past and my hearing was normal last time he checked it.  After doing a hearing test, he verified my Hearing was severely decreased in my right ear. I explained to him, I also feel "foggy" and I have problems concentrating, was having vertigo, and vomiting. I am not sure if that is because of the constant sound in my ear that distracts me but it is a definite problem and interferes with my work. I cannot concentrate. He started me on Steroids (Prednisone) 60 mg a day for 7 days, then 40 mg for 3 days, then 20 mg for three days, Antivert 12.5 mg three times a day as needed, and Zofran for the vomiting if I needed that.  I have not experienced anymore vomiting and the Vertigo has been very limited. Mostly when I lay down now instead of when I stand up.  My blood pressure has also been slightly elevated, but it could be from the Steroids.   I was scheduled to take the 2nd Pfizer Vaccine on 01/09/21. Since I was receiving the high doses of Steroids, I was concerned that the vaccine would not be effective or may interact with the steroids so I went to my family doctor 01/08/21, for a visit. He said he would check and let me know if it was contraindicated for me to take the Vaccine on high doses of steroids. When I did not hear from him, because I had to take the vaccine the next day, I called the Pharmacy and talked to someone there and they told me the agency was still recommending you take the Vaccine even if you are on the steroids. I received the second Pfizer Vaccine on 01/09/21.  My hearing is now coming and going but I can hardly hear anything out of that right ear. . There is a constant noise, like a roaring, in my head and I still have problems concentrating. I have had no more vomiting and my vertigo has hot been as severe but I have experienced some at times.   I reported to the Pharmacy the day I received my vaccine, 01/09/21, about the things I had experienced this since my first vaccine. They took my information and said they would call me but today is 01/12/21 and I have not heard from them yet so I thought I would go ahead and report this. I am concerned this was an adverse reaction to the vaccine. I return to the doctor 01/20/21 for a repeat hearing exam.   The Doctor expressed this condition could be a permanent and disabling  issue but currently being treated and will follow up with more testing.   I am also concerned about how the second vaccine affected me because I was receiving the high doses of Steroids at the time I received it.    I am sending this from a work email so if you reply, please reply to personal email.
