The United States surpassed 300,000 coronavirus deaths on Monday, the same day that saw the first doses of Pfizer's COVID-19 vaccine distributed to select health care workers in several states. 

As of Monday afternoon, the U.S. had tallied 300,267 coronavirus deaths, according to Johns Hopkins University data. Health and Human Services Secretary Alex Azar made several appearances on Monday to mark the momentous occasions in vaccine news, but also used it as an opportunity to warn Americans against letting their guards down. 

"We need you to be vigilant, we need you to do that because we want everybody who is here now to be here next year for the holiday season," Azar said. "Now is not the time to let our guard down. This is not the end of our battle against COVID but today marks a critical milestone in the ultimate defeat of COVID-19."
