Write-up: (I''m a physician who received the vaccine at my medical clinic). 5 minutes after receiving the vaccine, I felt very dizzy and faint. We checked my BP (which is usually 120/70; I do not have hypertension), and it was 190/120, HR 120-130 bpm. We rechecked it several times and it stayed there. After 5 minutes, I suddenly felt better and my BP had dropped to 140/70, HR 70. I felt exhausted. No other problems. They watched me for 30 minutes and I felt fine. I had my husband drive me home. As we were driving home (now one hour after the vaccine), I realized that my throat was closing up. I was breathing fine but I realized I was having an anaphylactic reaction from the vaccine. I have never had any allergic reactions before to vaccines, etc. He drove me back to the emergency room of my hospital, where they diagnosed me with an allergic reaction/anaphylaxis to the vaccine. They gave me emergently IV solumedrol (steroids), pepcid, and benadryl, which fortunately worked immediately. They observed me for several hours and I was fine. They sent me home. The next morning, I felt exhausted and my throat was hoarse and sore, but that went away several hours later. It was a terrifying, terrible experience. I thought I was going to die. I had to pay $1000 out of pocket for the ER deductible.
