To borrow bae's phrase from another thread, don't use reason and logic! I don't believe any previous administration would have gotten it 100% right, but you had to know this one would foul it up.
If I remember my biology correctly, the issue is that the common cold mutates very quickly, so developing antibodies for one strain can be of little help for the next one. The same with the "common" flu -- there are enough strains of it that the flu shot recommended annually is an educated guess at which strains will be most prevalent in a given flu season. What I've read so far about this coronavirus, though, is that it seems to be a slow mover, which could help in developing a vaccine.Originally Posted by ApatheticNoMore
