Nothing like this has ever happened in the history of modern medicine. As my American Enterprise Institute colleague, former FDA chief Scott Gottlieb, told me, “We’ve never really had this level of development work undertaken over such a short period of time with so many successes. This is a singular achievement. I can’t think of any historic proxy.”

So why has Biden refused to acknowledge it? On Monday night, in a speech hailing his electoral college victory, he ended by noting that we had just passed a “grim milestone” of 300,000 covid deaths. But he said nothing about the historic vaccinations that were administered that same day. It was like ignoring the moon landing.

Biden has criticized Trump’s pandemic response failures, so why not give the president credit for this unadulterated success? Because that would mean acknowledging that, for all Trump’s flaws in managing the pandemic, he is also responsible for ending it. And Biden is saving that credit for himself.

Perhaps, given Trump’s terrible behavior, Biden is in no mood to praise the president. But it’s not about Trump; it’s about Biden delivering on his promise to reach out to his opponent’s supporters and bring Americans together. If he truly wants to unite the country, he should give credit where credit is due — and pledge to continue Operation Warp Speed.
