Well, it does according to a leaked preprint someone posted on twitter that did not receive any peer review, was not published, and for which primary data is very well hidden. For a critique of a lesser number from yet another leaked preprint with the same status that only concluded 89.4%, see https://twitter.com/ZoeMcLaren/status/1363582050775744515 https://twitter.com/ZoeMcLaren/status/1363582050775744515 The bottom line is: results are positive, but every single one reported in headlines is likely overstating. 70% RRR (relative risk reduction) efficacy is supported by data, if I understand it. >80% or <50% is not - at least not with publicly available data.
