itchiness has come back; itchiness has come back; Not feeling well/ doesn't feel well; very warm; dizziness; nausea/ slightly nauseated; She had a lot of nausea and was treating herself as if it was Meniere's but it could be that or vertigo; This is a spontaneous report from a contactable consumer (patient) from Pfizer-sponsored program, COVAX US Support. An 80-year-old female patient received BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE), via an unspecified route of administration on 08Jul2021 (at the age of 80 years old) (Batch/Lot Number: EW0175) as dose 1, single for covid-19 immunisation. Medical history included rash, breast cancer diagnosed in early 2020, cancer surgery, Meniere's attack, itchiness and finished with her radiation in Aug2020. The patient has no concomitant medications. The patient previously took estrogen and experienced drug allergy, and 3 aromasins that caused the body rash which included anastrozole (ARIMIDEX), letrozole and a third one but she can't remember the name of it, it started with an "S". The patient had her first dose of the Pfizer COVID 19 vaccine on 08Jul2021. She was scheduled to have the second dose on 29Jul2021 but did not go due to not feeling well on 28Jul2021. The patient said it is strange because she has Meniere's, an inner ear imbalance, and she had some dizziness like a Meniere's attack, but it wasn't. She had a lot of nausea and was treating herself as if it was Meniere's, but it could be that or vertigo. It was confusing. She called her doctor who said that they didn't feel like it was a delayed reaction to the COVID vaccine. She still has slight nausea but not much. She didn't throw up and has had no problems eating or holding anything down, it was strange. This began right after the first vaccine in that evening (08Jul2021). She got very, very warm and she did get dizzy and slightly nauseated. That lasted about two days and then this last attack started on Wednesday, the day before she was supposed to go for her 2nd dose. She confirmed this is still ongoing, but it has improved. She then clarified and said that it started on Wednesday, 28Jul2021, and it lasted all through the weekend. She was taking meclizine for the dizziness and Zofran for the nausea and then she called the physician this week. She finally felt better by the time they called her back. She says she is not going to worry about that though. She confirmed that she developed Meniere's prior to her COVID vaccine, she has had it for quite a while. Prior to all of this, she had her breast cancer diagnosed at the beginning of the lockdown. When she finished her radiation, she was to start on antiestrogen medication and with all 3 of the aromasins she had a horrendous body rash. She had cancer surgery and finished with her radiation in Aug2020 and she was allergic to the estrogen mediation. She had a bad rash and was unable to go get her COVID vaccine until now. When she saw the dermatologist, he said not to go for the COVID vaccine because she could have an even more severe reaction at that time. That's why she delayed getting vaccinated. She didn't get a rash after the 1st dose, but her itchiness has come back. It took 6 months for it to disappear before she could be vaccinated. When probed for further information, names, NDC, lot numbers and expiry date, on the Aromasins that caused the body rash, the patient stated that the first was Arimidex that she had right after surgery and she has none left of that to provide further information. The second one she was happy with because it lasted for 3 months for a rash broke out, that was letrozole. She had waited a while because she figured that her body would get used to it, but it didn't. From Jan2021 to Mar2021, she was in bad shape and she saw a dermatologist. Then her oncologist gave her a third one but she can't remember the name of it, it started with an "S" and it only took 6 days for that one and she said she is not doing this to herself again so she stopped that. Her oncologist said that he has never had patient that has been allergic to all 3. She would like to reschedule the second dose, but she wanted to see how long she could go between doses before she had to restart the vaccine series. She relayed that she has an elder care assistant who schedules her appointments and that it has to be scheduled at the hospital in case she has a reaction. She stated this is due to the fact that she was diagnosed with breast cancer in early 2020 and they tried her on 3 different medications that she had a reaction to and with the last medication the dermatologist told her not to get any vaccines because she may have a severe allergic reaction. She is going to try to get it scheduled for next Thursday or the 19th but it will depend on the appointments they have available. The patient wanted to know if she would have to start the series over if she waited that long to get the second dose. The patient was told that it would be ideal to receive the second dose of the vaccine as close to 3 weeks from the first as possible but when that is not possible then it is preferred to have it within 6 weeks. The patient stated that maybe she could get a booster later on and she was told that a third dose is not recommended at this time but may be available in the future. The outcome of the event "itchiness has come back" was unknown, while the other events were recovering.  Follow-up attempts are completed. No further information is expected.
