MI Dendream,
Thanks for your comment and perspective. I have no reason to doubt your experience and do realize that if this scenario I suggest happened it would have been rare to possibly precedent setting. I fully understand those who consider this a stretch of the imagination at best. However, I believe the blind was kept. The assignments were given to someone else to handle. Cognate Germany no longer exists so who is administering the vaccine assignments? By the way, even if PFS was questionable, 1st half OS may still have been the basis for deciding SOC was inferior by comparison. Still, as I read your other post your rational makes sense for that possible if not more probable situation. Best wishes.
