President Biden announced Tuesday that the U.S. should have enough vaccine supply for every American adult by the end of May. Last week the Food and Drug Administration finally approved Johnson & Johnson’s vaccine, and this week J&J struck a deal with Merck to manufacture the single-shot J&J vaccine as well. With the Moderna and Pfizer shots already going into more than a million American arms each week, thousands of lives will be saved.

It’s important to appreciate what an achievement this is. Critics scoffed when President Trump set a target of having a vaccine approved by the end of 2020, and Kamala Harris suggested she might not take a shot recommended by the Trump Administration.

The Biden-Harris Administration has now changed to full-throated encouragement—though not before continuing to trash the Trump efforts. White House aides have suggested that they inherited little vaccine supply and no plan for distribution. Both claims are false.
