Good morning, NBC News readers.
The search for a COVID-19 vaccine enters a new chapter as a New York EMS worker reflects on the pandemic's horrors amid concerns over a second wave.
Here's what we're looking at this Tuesday morning.
A leading drug just hit a key benchmark in the quest for a coronavirus vaccine
The quest for a COVID-19 vaccine reached an important juncture Monday as Moderna Therapeutics began the first phase 3 trial of a COVID-19 vaccine candidate in the U.S.
Phase 3 is the final stage for a vaccine, so it is meant to answer the big question: Does it work to prevent COVID-19?
"This is the main event, if you will, in drug development," said Dr. Stephen Hoge, president of Moderna, a biotech company in Cambridge, Massachusetts.
Moderna has partnered with the National Institute of Allergy and Infectious Diseases for its vaccine research.
As many as 30,000 volunteers will be recruited at nearly 100 research sites across the country in Moderna's phase 3 trial. Half of the participants will receive the vaccine, and the other half will receive a placebo.
A new study released Monday reviewing 20 years of data found that U.S. vaccines are remarkably safe, thanks in large part to ongoing surveillance after they hit the market by the the Food and Drug Administration.
"Most studies like this show a complicated picture, but here, we saw almost no complexity at all," said the study's lead author, Dr. Daniel Shepshelovich. "Vaccines are safe."
Here are some other COVID-19 developments:
- Trump’s national security adviser, Robert O’Brien, has tested positive for the coronavirus.
- A coronavirus outbreak among players on the Miami Marlins has called Major League Baseball's season into question just days into its long-delayed start.
- Notre Dame has withdrawn from hosting the first 2020 presidential debate, citing the coronavirus threat.
- Poll: Mask-wearing divisions remain even as coronavirus cases spike.
- Track U.S. hot spots where COVID-19 infection rates are rising.
- The U.S. death toll from the coronavirus has surpassed 148,000 according to NBC News' tally.
'End of life as we know it': EMS captain on pandemic's horrors amid concerns of second wave
At the height of the coronavirus pandemic in New York, emergency medical services Capt. AJ Briones' teams were fielding nearly 700 calls a day.
Before the pandemic swept through, Briones said their typical call volume was somewhere around 300 to 400 calls a day, but during the peak, calls doubled at times.
“We did a month's worth of cardiac arrests in three days, three months worth of intubations in three days," Briones said. "It was really a hard time for anybody. I don't care how seasoned you were."
Now with cases down in the state, his EMS teams can sometimes catch their breath for a moment. But with cases rising rapidly around the country, Briones reflected on the virus' devastating toll, how far New York has come and his concerns about a possible second wave.

'We are the legacy': John Lewis lives on in the generations of young activists he empowered
For all the achievements of his 67 years of service, Rep. John Lewis' commitment to inspiring the next generation of leaders and activists may be his most significant and lasting contribution.
As an activist fighting for racial equality, Lewis, at 23, was the youngest speaker at the 1963 March on Washington for Jobs and Freedom. Two years later, he put his body on the line for voting rights on "Bloody Sunday" on the Edmund Pettus Bridge in Selma, Alabama, thinking he might be killed at 25.
Even before his work on the national stage, Lewis was a young preacher in his teens, and he led other students in anti-segregation work.
But as he grew into an elder statesman of the civil rights movement, Lewis actively looked to young people to continue his work.
"We are the legacy of Congressman Lewis," said Rachelle O'Neil, who joined Lewis' staff as a constituent services representative when she was 32 and worked with him for 18 years. "There are hundreds of us around the country who have been impacted by him."
