I hope hydroxychloroquine turns out to be helpful. There's a lot of variables when it comes to treatments and trying to do a real study of efficacy -- especially in the middle of a pandemic! But, I am also concerned that if we put too many eggs into the hydroxychloroquine basket without real evidence of its efficacy, we might miss a critical window for developing and trialing other therapeutic drugs.
I'm not sure what the answer is, but I do think being desperate and just throwing hydroxychloroquine at every single COVID-19 patient that requests it (or gives permission for it to be used on them) will make it more difficult to determine if it works. It's a terrible catch-22, but we really do need proper studies with tightly defined control groups.
