The counterpoint to this is that you can't just wait forever before making a decision. At some point, you'll have to do with imprecise data, and for a pandemic that is developing very rapidly, you can't just sit back and do nothing (well you can, but then you have to make an argument for why this is a good option).

As to the point of whether utilitarianism is a good ethical framework... well, at least no non-consequentialist ethical framework has ever convinced me. A naïve reading of utilitarianism has its problems, of course, but those can be accounted for; but the classical Kantian conundrum of not being allowed to lie to a murderer seems silly to me. Plus saying "principles matter" has just as many problems as the utilitarian approach, as nobody will be able to agree on those principles.
