There was a WHO press-conference about a preprint, and more information is coming this week.

That is the totality of information.

I don't have access to the FT article as it is paywalled, but some less meaningful sources have summarized it and use the "modest evading" phrase.

As I don't care for the conversation as I lost all energy going over this stuff last year when the same thing happened, a preprint is not peer reviewed and is necessary to become peer reviewed. Hundreds of thousands of people will die before that happens. Make your own decisions.
