re: Fully vaccinated parents, both tested positive....Updated OP

100% agree, it should be standard of care, along with some of the other recommendations (baby aspirin, to reduce risk of blood clots, steroid where there aren't any other contraindications, recommended vitamins and expectorant....
When i was diagnosed positive, they sent me home and said take tylenol and ibuprofen alternately and a zpack Rx (take this in a week if you're still feeling bad).....it's like they want it to get worse so you have to be hospitalized....
