It will be interesting to see if this will mutate into less harmful variants, or, with vaccines go the way of Marek's disease, and become more lethal. This is a fascinating global experiment that will determine our policy for decades either way.

We ought to be hustling on a non-leaky version, and perhaps that will be the policy lesson learned.
