Fwiw, my vague memory is that some other people at CHS, including Tom Inglesby (the director) did better than Adalja. I think Inglesby’s Twitter was generally pretty sensible though I don’t have time to go back and check. I’d guess that, like most experts, he was too pessimistic about travel restrictions, though. Maybe masks, too?
I do think CHS should get some credit for arguing for taking pandemic response very seriously early on. For example, I think Tom had some tweets arguing for pulling out all the stops on manufacturing more PPE in January 2020.
Note—I’m a bit biased since I was working on biorisk at Open Phil the first time Open Phil funded CHS.
