Even though many breaktroughs have been made, I don’t think all pieces are in place yet. Anyway, we need HCQ or quercetine to get the zinc into our cells. But even then, in early Chinese in vitro studies of many traditional and cheap off patent drugs (the kind of throwing spaghetti against the wall and see what sticks) many compounds, like ivermectin and HCQ were promising. (I remember artemisia and praziquel, but there were many more, a lot of them not even with western names). We have not seen many follow up studies. They are not funded. When the news about ‘covid organics’ from Madagascar, consisting of artemisia, probably coffee and/ or another tropical herb, became somewhat public, The WHO warned against it, without any research, within one day!
So I think, even if Chris lowers the frequency of his corona updates, he is not done yet for a long time coming!!!
