She had an anaphylactic reaction/shock and was hospitalized with the 1st shot. She was highly allergic with the vaccine almost killed her. The patient experienced allergic reaction which went into Anaphylactic shock on17Mar2021. It happened 45 minutes after receiving the vaccine. The patient saw Pulmonologist on 19Mar2021. She thought he would just give her a shot and a breathing treatment and he did, but said she needed to get to the hospital because it was not asthma, it was the vaccine. On 19Mar2021, she was hospitalized. She has Asthma already previously. At home she had a nebulizer. She has Lung cancer and had it prior to getting vaccine. She went and got the vaccine which is around the corner from her house and all the doctor's finally agreed she should get it because the virus is really bad, so she got it and they knew she was high risk and kept her for 30 minutes. She came home 5 minutes from there. When she got home and sat down. All of a sudden, she could not breathe. She was wheezing like crazy and thought she was having an asthma attack (She lives 50 miles from her doctor. That is why she did not go and thought she was having asthma attack). She got her nebulizer and started doing a breathing treatment. It wasn't getting better and she took a handful of steroids. She did it around the clock and did not think it was vaccine, but asthma. The medicine's were not working. She was taking Brovana inhaler in nebulizer and Budesamide in nebulizer as well. Budesamide Lot 11920 Expiration Mar2022, (Manufacturer withheld), Brovana Lot S20C019, Expiration Sep2021, (Manufacturer withheld). Steroid was Methylprednisolone. Pill 4mg. IT is in a pharmacy vial. Lot and expiration are unknown. Count size not provided. They eventually had to admit her again because the steroids were not working and they had to increase dose and give it to her IV in the hospital. She is not good moving around and got out of breath. She needed IV steroids. The ones at home were not getting it. She would send a sample. She took 10 of them in a couple of days to get breathing under control. It was only working a couple of hours. You should only do nebulizer once or twice a day and she was doing it every couple of hours. The pulmonologist admitted her within an hour. Because they were increasing her steroids at home and she was not getting better she needed higher dose and they gave her higher dose. This time they also gave IV antibiotic which was different. The patient could not breathe again on 08Sep2021 and had to be re-admitted. The event required a visit to Emergency Room on 08Sep2021 and was given IV Steroids and IV Antibiotic and Breathing treatments.
