An 83-year-old female patient received first dose of BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE, Solution for injection, lot number EL9262, expiry date unknown), via an unspecified route of administration, on 20Jan2021, at a single dose for COVID-19 immunization. Medical history included ongoing allergies (She normally gets an allergy shot for mold and stuff. She had one 8 days prior to getting the vaccine. She has not gotten one since. She is due but she cannot get it until this clears up. She is unsure of the name of the allergy shot that she gets. She had all the allergy tests years ago and has been going for the last 4 years or so. For things like mold, dust, cockroaches, grass, and trees) for which receiving allergy shot, ongoing High blood pressure, ongoing Reflux, and ongoing Osteoporosis/osteopenia. Osteoporosis runs in her family, she does not have it yet but she had Osteopenia (She started young).

Patient had the first shot of the vaccine last Tuesday. She stayed for half an hour and was fine. She left there and 10 minutes later while driving she started getting itchy around her face mask. She thought it was the mask irritating her skin. As the day progressed her cheeks and under her chin were getting red and itchy. She took Benadryl and the next day it got worse. She called the doctor and they put her on 20mg Prednisone two times a day. That was a week ago Tuesday. She called her allergist and he thought it was the poly glycol peg that is in the vaccine. He will test her after it is all out of her system. Both her regular doctor and her allergist told her not to take the second shot because it was too close a situation. She did not have an anaphylactic reaction, but if she had not jumped on it right away what could have happened. She is wondering if company has any data on the efficacy of the first shot if going on Prednisone right after? She started the Prednisone the next night. She is tapering off now. She still has a little bit of heat on her face and itching under the skin. So, apparently, she had an allergy to the vaccine and was told not to get the second shot. Patient clarified that she did not get the vaccine last Tuesday. She got the vaccine last Wednesday which was 20Jan2021. She said the reaction started about 40-45 minutes after receiving the dose. She has improved about 90% since starting the Prednisone. This morning her face is a little red. She is currently weaning off the Prednisone. Her face was red and it feels a little hot. She is down to 10mg twice a day. She had started the Prednisone the next day on 21Jan2021. She started the wean yesterday. This morning her face is a littler red on her cheeks. The vaccine seems to be taking a long time to get out of her system. NDC, lot, exp are unknown for the Prednisone as it is in a pharmacy vial.
