she is short of hearing; losing her breathe; This is a spontaneous report from a contactable consumer (patient) from a Pfizer sponsored program. An 83-year-old female patient received the first dose of BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE; Lot number: unknown) via an unspecified route of administration on 29Jan2021 at single dose for COVID-19 immunization. The patient's medical history included: Stage 3 lung cancer, radioactive therapy on 25Dec2020 to 31Dec2020 (Also reported as 2-days prior to her 1st vaccine shot, the nurse gave her 2 radioactive therapy and the last one was 31Dec2020), immune therapy on 01Jan2021 (7 weeks' worth received all in 7 days), and steroid therapy on December 2020 and Jan2021. The patient had terrible reaction from the immune therapy on an unspecified date which include all the skin of her mouth had ulcers, had such sickness, diarrhea, a rash all over the face, had headaches, was so fatigued, no energy and could not get out of bed. Patient felt better in the past few days. Other medical history included had a bad fall, two broken ribs and needed hip replacement surgery from unspecified dates. She lives alone and received 700 units a day of steroids for 10-days last December.  Family history included lung cancer runs in her family (sister and brother died of lung cancer, other sister got it too).  Patient stated her doctor called her in 2 days before and stated her next step was immune therapy, she has had massive doses of radioactive before, she had 7 weeks of that in 10 days, and had an extreme reaction from that, the last one was 31Dec2020. Concomitant medications were not reported. The patient stated she refused her immune therapy, as she wanted the vaccine. It was put down as she did not want it. The patient reported that nurse there then said she was going to be put on unspecified steroid, which she never had before. Her friend picked up the prescription and, without reading everything, and she usually does, she took two of them. It said take all 6 that evening, but she took 2 then read and it said not to take with any vaccine. She stated that the nurse knew how she stressed she wanted the vaccine, and so she had the COVID vaccine. She just had the two steroids, and she said she wanted to wait until Mar2021 until she considered getting immune therapy, but the nurse booked her for 26Feb2021, and she had her second vaccine from Pfizer scheduled on 19Feb2021 one week apart. She asked if that is too soon, and does she need to put off immune therapy again. She read it is 2-3 weeks between, she wanted to have this verified. Patient stated she supposed to take 6 steroids then 5 and so on. She took 2 pills then as she was reading information regarding the vaccine, she did not take anymore.  Last week is when she took the two steroids, she won't take them. She called a pharmacist, who said do not take them. The doctor's office, the nurse, gave them, after she told them she would have the vaccine. She stated she was furious, but she was getting this all the way down the line. She put the steroids away, she said she was not taking them, she talked to someone in the medical field and told her how she felt, and she agreed.  Patient asked if it will be ok to have the immune therapy at that time and soon after getting the vaccine if it would be effective. She mentioned that at her age she is more concerned that she gets that vaccine and she wants to delay having the immune therapy until March given the horrible reaction she had before. She tried and tried to have this conversation with her doctors, but she does not have all that technology and they are only offering remote appointments. Patient stated that she had no problems from the first dose of the vaccine stating she did not even feel the needle. She has been exactly an hour on the phone. The patient stated that she was losing her breathe after speaking at this time during the call on 05Feb2021. She also stated she is short of hearing (onset date unknown). Outcome of the events was unknown.  Information on the lot/batch number has been requested.
