Here's a commercial opportunity to sell millions of roses of AZ vaccines that we could get stuck with as they exceed the use-by date and by possible millions, given the ramped up production volume? I see no particular use in trying to tell desperate folk what to do! Given the available options actually on the table! All we should and can do, is offer to help in any way available to us, including the possible gift of millions of AZ doses. And as they find as many others have? That the Chinese vaccine is not particularly efficacious? Our gift? Would be remembered!
