Bob, that article has a fair amount of bad info in it.
Trump did not "develop" any vaccine. Pharmaceutical companies did.
He did throw plenty of borrowed money at the problem and cut many regulations (safety measures) to help get it approved at "warp speed". The question remains as to weather that, or his continuous downplaying of the problem ("it will just go away") was prudent? The money wouldn't have had to have been borrowed if such huge tax relief hadn't been given to big business, wall street, real estate developers, and the very rich in general to the tune of around 4 t if I recall correctly.
So it might be said that Trump "assisted the speed of development", but that is all.
Biden did credit "the previous administration" with "warp speed" in more than one of his earliest briefings I remember that quite well.
He also mentioned the total lack of any distribution system having been set up...which the former admin had what... ~a year to set up.
The article also fails to mention all the funds Trump cut from the prevention/identification/control side of the equation before this all happened, or his refusal to follow procedures already in place (the book) for such incidents, and just "wing it" with whatever fancy came to his attention next.
PPE manufacture & distribution/logistics under Trump was an uncoordinated disaster. Putting His incompetent son in law in charge of this was a huge mistake where cronyism & politics ran rampant over common sense, and immense amounts of money were handed to political allies/supporters for things that never got produced, or delivered. Leaving the States on their own to have to find supplies & bid against each other & other countries, only to have the Trump admin step in, confiscate, and redirect already paid for shipments that were on the way to one State, and have them sent to a State that showed higher political support levels.
Trump waffled between "it's nothing...it'll go away on its own very shortly" to "no one has ever had to deal with a problem this size, nothing is my fault, unprecedented!, re-elect me!"
Yes, by all means, let's give credit where credit is due.
