Who’d have thought that an Oxford vaccine would confidently persuade everyone it was useful but then turn out to have bullshitted its way through the test

New results on a possible COVID-19 vaccine from Oxford University and AstraZeneca suggest it is safe and about 70% effective, but questions remain about how well it may help protect those over 55.

Basically, according to new trial data published in the Lancet, Oxford University and its partner AstraZeneca are, yes, hoping to get the regulatory nod for their vaccine on the basis of its 70% efficacy, which was achieved after collecting trial results from Brazil and the UK. However, it seems that the vaccine’s efficacy is 90% in a subset of the vaccine trial candidates who got a half-dose first — while the vaccine only has 62% efficacy for the majority.

1. From what I get from reading, all the vaccine trials to date have been done

with youngish, relatively privileged participants. So the question of how well they work for the general population is applicable to all the vaccines, not just the Oxford vaccine.
