President Biden marked the milestone of the United States administering 300 million coronavirus vaccination shots in 150 days during a speech Friday from the White House. He also acknowledged that there is more work to be done in the battle against the pandemic.

“The truth is that deaths and hospitalizations are drastically down in places where people are getting vaccinated. But unfortunately, cases of hospitalizations are not going down in many places,” Biden said in pleading with Americans to get vaccinated.

Vice President Harris is also focusing on the pandemic by visiting a pop-up vaccination clinic at a Baptist church in Atlanta and attending a “vaccination mobilization event” at a local university.

The focus comes as coronavirus cases are declining and jurisdictions are dropping restrictions, but as the country is also on track to fall short of Biden’s goal of administering at least one vaccination shot to 70 percent of adults by July 4.

Here’s what to know:

  • Biden called on Americans to commit to “eradicate systemic racism” in a proclamation issued Friday ahead of the observance of Juneteenth, the nation’s newest federal holiday.
  • Former vice president Mike Pence was heckled onstage at a conference of social conservatives, with a dozen or so activists shouting “traitor” as he introduced himself.
  • The White House laid down a tougher marker against raising the federal gas tax to help pay for an infrastructure package, saying it would violate the president’s promise not to raise taxes on people making less than $400,000.
  • Catholic bishops voted to create guidelines on the meaning of Communion, a move that could be an early step toward limiting the serving of the Eucharist to Biden and other politicians who support abortion rights.
  • Biden announced his plan to nominate Christi A. Grimm as the inspector general of the Department of Health and Human Services, seeking to elevate a longtime government employee whom then-President Donald Trump sought to supplant last year.
