Yes, as I've described yesterday, this is a recommendation for more careful adherence to the manufacturers' testing protocols. I've explained that the new case curves for the entire US, as well as virtually all the individual states (including ALL the Biden-hating GOP red states), all plateaued around Jan 07-08, 2021. Then all of them started to display drastic decline between Jan 07 and Jan 12, 2021. The huge decline in new cases started one to two weeks before the "new" WHO memo and the Biden inaugural on Jan 20. And none of the curves showed any changes in trajectory after Jan 20, suggesting that the changes in the new cases started way before Biden took office and were not affected by his inaugural and the new WHO memo.
It would be insane to believe that any of the red/GOP/Trump states would want to do anything to please Biden and to make Biden look good. This is especially true when, between Jan 07-12 (when the drastic decline started), the Trump administration still held all the vaccines in their hands as important bargaining chips. Just look at how many red states still supported Trump on Jan 06.
