Half of U.S. adults are now fully vaccinated, less than six months after Pfizer got the first emergency authorization for a COVID-19 vaccine.

By the numbers: More than 287 million doses have been administered in the U.S.

The big picture: Just 39% of the overall population is fully vaccinated if you include people under 18.

  • The current rate of 1.8 million daily doses reflects a decline since mid-April, Bloomberg reports.

Teens should see widespread availability before school starts in the fall.

  • Moderna said today its vaccine is safe and 100% effective at protecting against COVID in people between ages 12 and 17, citing a Phase 3 trial of more than 3,700 participants.
  • Pfizer's vaccine received an FDA emergency use authorization for 12- to 15-year-olds earlier this month. It already had approval for use among those 16 and older.

About 14% of the nation's kids ages 12-15 have received their first shot, AP reports.

  • Among teens ages 16 and 17, that number goes up to 34% and about 22% have had both shots.
  • Depending on the state and even county, minors may be required to have a parent present.

What's next: Pfizer plans to apply for emergency use for kids ages 2–11 in September, NPR reports, and Moderna is in the trial phase for kids.

The bottom line: It increasingly looks like most who want a vaccine may be able to get one by year's end.

Report: U.S. has discarded over 15 million COVID vaccine doses since March

The U.S. has discarded at least 15.1 million doses of COVID-19 vaccines since March 1, according to government data obtained by NBC News.

Why it matters: The data comes as the Delta variant spreads rapidly across the country, and after the Biden administration announced plans to roll out booster shots — renewing the need for an ample vaccine supply.

The CDC is asking unvaccinated people to not travel this Labor Day weekend, citing the surge in COVID-19 cases largely driven by the Delta variant.

What they're saying: "First and foremost, if you are unvaccinated, we would recommend not traveling," CDC director Rochelle Walensky said during a White House COVID-19 press briefing Tuesday.
