White House: Over 500,000 new shots recorded Friday, highest since July 1

The United States recorded more than half a million new COVID-19 vaccine shots on Friday, the highest number since July 1, White House deputy press secretary Karine Jean-Pierre said.

Why it matters: The Delta variant is continuing to spread across the United States and it now comprises over 80% of the coronavirus cases in the country, Jean-Pierre said. A report from the Centers for Disease Control and Prevention noted that "vaccination is the most important strategy to prevent severe illness and death."

• Coronavirus cases have been increasing since around late June, according to CDC data.

State of play: Jean-Pierre also reported that the number of people getting vaccination shots is up by 30%.

What they're saying: "This is an encouraging sign, but we need everyone across the country to have a conversation with someone they know who is unvaccinated about getting the shot," Jean-Pierre said during the press briefing.

• "This is how we will stop the spread of the Delta variant," she added.

Of note: Jean-Pierre clarified that "a national vaccine requirement is not under consideration" by the Biden administration.
