Same could be said for Chemotherapy, yet nobody is calling to stop the use of it.
Depending upon the chemotherapy, you're absolutely right. I'm not calling for stopping the use of hydroxychloroquine/chloroquine, and I would most definitely treat Covid patients with it. That said, like most therapies for potentially lethal diseases, I do not expect it to be a miraculous cure. I hope it is, but it is unlikely to be.
