Biden administration purchases 200 million additional vaccine doses

Context: The Biden administration said last month that it planned to buy an additional 100 million doses each of the Moderna and Pfizer-BioNTech vaccines.

What they're saying: "We need more people to get vaccinated to beat this pandemic," Biden said Thursday.

• "We've now purchased enough vaccine supply to vaccinate all Americans, and now we're working to get those vaccines into the arms of people," Biden said after he toured the Viral Pathogenesis Laboratory at the NIH complex that developed the COVID-19 vaccine manufactured by Moderna.
• "The new strains emerging create immense challenges, and masking is still the easiest thing to do to save lives," the president added.
• “As the President directed, we are expanding our supply of COVID vaccines to protect people as quickly as possible,” acting Health and Human Services Secretary Norris Cochran said in a statement.

Of note: It's unlikely the purchase will make the vaccine widely available sooner than originally planned, but it may prevent shortages later this year, per the Post.

Zoom out: The Biden administration announced last week that the first federal mass vaccination sites will open in Oakland and Los Angeles later this month.

• More than 32 million Americans have received at least one dose of a vaccine, according to data from the Centers for Disease Control and Prevention.
