Well Derek, you ain't gonna find any nuances in Keith's announcements from the mountain. Did you really expect any? He lumps it altogether just to stir the pot
Personally I'd be happier with Russian vaccines if (!) my family had to take it, rather than concoctions from the west. I've read enough on the subject to be cautious. I doubt Keith is likely to have read much on it, otherwise he would debate it ... otoh probably not, but he would stir the pot nevertheless.
