I worked as an RN in MA when Covid first hit. I was one of the first nurses to take the first Covid patient. It was the last week of Feb 2020.  The doctors decided to grant the patients wishes to be treated with HCQ and Azithromycin. Our doctors were very concerned that it wouldn’t•••. I gave gave the him the medications around 4pm and by 10pm he made a remarkable recovery. He went from being on a non rebreather O2 mask looking like he would need to be intubated to sitting up comfortably with just a nasal cannula eating apple sauce and watching TV. It was amazing to see and then after that we were told we could never give it again. That’s when I woke me up to Covid being possibly something other than a virus.  
BTW Remdesivir put most of my patients in Kidney failure so I refused to give it anymore and walked out on 9/2021 saying goodbye to my 20+yr nursing career. Absolutely no regrets.
