She took some Benadryl. Her body shook all over and was chilled. She stated that she should have gone to the hospital). There were no other vaccinations taken (within 4 weeks) prior to the COVID vaccination. She took the first dose of the BNT162B2 vaccine on 07Jul2021. On an unspecified date in 2021, the patient experienced blisters in throat, horrible hacking cough, fluid in the back of the throat, real sore throat, phlegm/ productive cough and fluid behind ears. Clinical course: The cough started a month later (it did not start directly after, it was 3 or 4 weeks after the Covid-19 vaccine). She assumed it had nothing to do with the vaccine. She started having a cough and fluid in the back of her throat. She finished the Zithromax Pack last week. She went to the doctor and they checked her for Covid, flu and strep which were all negative. They diagnosed her with fluid behind her ears and blisters in her throat. She had a real sore throat, but was not saying that it was due to the shot. That was several weeks after.  She had a horrible hacking cough which almost choked her to death and took her breath for several days but she was getting better. She spit up phlegm which was white, with no color or tinge. She still has a little bit of the cough and has some phlegm that is all clear. She no longer has fluid in the back of her throat. She no longer has fluid when she coughs. Her throat was still sore. She was not coughing now. The hacking coughing was gone. She later clarified that the Zithromax was prescribed for the coughing and sore throat. They also gave her some other kind of shot, that was not a steroid (she does not know what kind of shot it was).  The patient did not require Emergency Room or Physician Office visit. The patient underwent lab tests and procedures in 2021 which included influenza: negative, lab tests: unknown, SARS-CoV-2 test: negative, streptococcus test: negative and weight: 113-114 lbs. The outcome of fluid in the back of her throat was recovered on an unspecified date in 2021. The outcome of hacking cough and phlegm was recovering. The outcome of sore throat was not recovered. The outcome of blisters in throat and fluid behind ears was unknown.
