We published a post on work at the University of California, San Francisco, to identify existing drugs that looked like they had the potential to treat Covid, as in at a minimum reduce the severity of disease (We Found and Tested 47 Old Drugs That Might Treat the Coronavirus: Results Show Promising Leads and a Whole New Way to Fight COVID-19). But that was before the vaccine effort was far enough along to look like it was likely to bear fruit.
As we’ve pointed out, the West has gone all in with the vaccine magic bullet approach, when that’s not a great public health idea, unless the goal is the low bar of keeping hospitals from collapsing. It’s unlikely that any vaccine that combats a respiratory virus will achieve the level of sterilizing immunity.
