I read the article. It stated for this experiment, the HCQ was useless and they stopped bothering to test it way back.
Maybe it’s ok for “prophylaxis...which apparently many medical types use it as a precaution...but apparently it’s not helping those who are really in trouble.
These “studies” fail to use zinc. Purpose of using HQC is to carry zinc into cells so RNA virus cannot replicate. Once you are in “trouble” it’s late. Although now it appears another cheap steroid Dexamethasone appears to work well in late stage.
