Yeah, there was a ton of news on that vaccine last week.

After a bit of push-back the laboratory acknowledged that this 90% efficacy was comparing a much younger vaccinated population than the one that got placebo.

That has put some doubts on the entire procedure (with countries forcing them to publish details), but it doesn't look like a real problem right now. Anyway that one high efficacy result is very likely flawed.

Anyway, what I get is that the important part is this: "Nobody getting the actual vaccine developed severe-Covid or needed hospital treatment."
