I had a mild case of COVID last year with a low fever and body aches. Went to the doctor, who took a mouth swab which resulted in a positive test result. The doctor prescribed Remdesivir pills, but before I received the pills I was well again, no fever or aches, but felt tired for a couple of weeks. I think that is common after COVID. I was not hospitalized and did not get a Remdesivir shot. I took the pills just to make sure. No kidney or other problems that I know of.
Sounds like people with kidney problems should not take Remdesivir, but it might mot be so bad for others, especially those who are not hospitalized.
I don't take the COVID "boosters" but do take vitamin D3 and chelated zinc.
Take ivermectin instead.
