Oxford University vaccine shows 70% protection

Duplicated with this one in the top? https://news.ycombinator.com/item?id=25184331

Note there is some confusion in the efficacy rates reported by the media.

I really don’t get the point of averaging two different dose regimens when only one of the two will be used in practice. The real news here is 90% efficacy, plus it will get even easier to mass produce because it will only require a half dose the first time.

Obviously they'll be a bit disappointed with those numbers, but I think the article undersells how big a difference the ease of storage will make. It requires a fridge instead of specialist cold chain equipment.

n=2,741 for the 90% efficacy dosing regime (involving a lower dose)

n=8,895 for the 62% efficacy variant

From my point of view, this is all very encouraging and actually lets me find redeeming qualities in this whole Corona crisis. While the SARS-COV-2 virus is certainly not to be trifled with, it's easy to imagine more serious virus outbreaks and I think after this pandemic is over, we will be capable of developing effective vaccines for many viruses in 6 months which would make us much more resilient in the future.

Correct me if I'm wrong but they ran 2 tests, and if you give someone a half a dose, wait a while then give a full dose, it's 90% effective?

So calling 70% is inaccurate?
