The CDC did fuck all, Trump kicked some major arse and got the military involved. However it's not surprising that you would totally downplay his major role in expediting the vaccines, bullshit is your best friend after all.
Yes, yes, I know, I know — this or that “fact-check” thingy on the web claims that Trump and his Operation Warp Speed had nothing to do with this or that development of this or that vaccine. I’ve read them. Most are outrageously petty, using weasel words like “full credit” or “partial credit” or nitpicking to deprive Operation Warp Speed any credit at all, with some focusing on details of one vaccine produced by one pharmaceutical company but ignoring details of others. If you want to navigate your way through them, then go for it. (For the record, PolitiFact did a pretty fair job in its evaluation.) It’s an infuriating exercise that immediately raises one’s B.S.-detectors. But those not poisoned by ideological bias and political hatred know in their hearts that Donald Trump deserves some major credit here.
Again, Joe Biden knows it as well. To repeat: “I think the administration deserves some credit getting this off the ground with Operation Warp Speed,” Biden acknowledged that as he and his wife stuck out their arms for their first vaccine injections in Wilmington. Again, that statement came eight weeks after Biden during the second president debate scoffed at Trump’s assurances that a vaccine was coming by the end of the year.
Biden got his by the end of the year.
