Clinical course: Caller stated that his wife got the 5th shot of the Pfizer BioNTech Covid-19 Vaccine last 07Apr2022 and stated after a few days, she started to have problems breathing. She went to the pulmonologist to find out if it was caused by the vaccine shot or "part of the problem". After a few days, she went to the hospital and she was there for 5 days and they did every test he could think of to see why she was having difficulty breathing and they couldn't come up with an answer to her condition and they put her on steroids (initially 40mg then changed to 20mg) but she never stops having problems with breathing. It only helped her for a couple of weeks and she was still experiencing difficulty of breathing.

He said he was waiting for her doctor to call and if doctor calls he will have to hang up. He said event started the 6th or 7th day after receiving the vaccine. She has been on oxygen since she got home from the hospital. He said oxygen doesn't help and she can walk 10 feet and then she has to sit down and the oxygen doesn't work. He said she can't taste and she is a good cook and it's affecting other part. He said she was on prednisone. He said she has been home for a couple weeks.
