Biden outlined a five-point vaccination plan Friday to ramp up rollout when he takes office.

On day one, he said he plans to instruct the Federal Emergency Management Agency to start opening the first of thousands of federally supported community vaccination centers across the nation. By the end of his first month in office, 100 of these centers will be open, Biden said, at places that are "convenient and accessible," such as school gymnasiums, community centers and sports stadiums.

"As we build them, we're going to make sure it's done equitably," Biden said. "We're going to make sure there are vaccination sites in areas hit harder by the pandemic, in Black and Hispanic communities as well."

Within the first month, his administration also plans to promote mobile vaccination clinics "to hard-hit and hard-to-reach communities in cities, small towns and in rural communities," he said.

Thirdly, the administration plans to "fully activate the pharmacies across the country to get the vaccination into more arms as quickly as possible," Biden said. This will include working with both independent and chain pharmacies to help people more easily make appointments, he said.

The fourth point of the plan involves ramping up vaccine supply through the Defense Production Act, Biden said.

"We'll use the Defense Protection Act to work with private industry to accelerate the making of materials needed to supply and administer the vaccine, from tubes and syringes to protective equipment," Biden said.

Lastly, Biden promised transparency on vaccine supply.

"We're going to make sure state and local officials know how much supply they'll be getting and when they can expect to get it so they can plan," he said. "Right now, we're hearing that they can't plan, because they don't know how much supply of vaccines they can expect at what time frame."

Biden stressed that his administration is not changing the Food and Drug Administration's recommended dosing schedules.

"We believe it's critical that everyone should get two doses within the FDA-recommended time frame. So we're not doing away with that availability," he said.

Ahead of planned remarks Friday afternoon on his vaccination program, Biden released the names of top members of his White House science team.

Dr. Francis Collins will continue in his role as director of the National Institutes of Health, Biden announced.

Biden also wrote a letter to Dr. Eric Lander, the presidential science advisor-designate and nominee for director of the Office of Science and Technology Policy (OSTP), tasking him to "work broadly and transparently with the diverse scientific leadership of American society."

Here are all the positions announced Friday by the Biden team:

-Dr. Eric Lander will be nominated as director of the OSTP and serve as the presidential science advisor.

-Dr. Alondra Nelson will serve as OSTP deputy director for science and society.

-Dr. Frances H. Arnold and Dr. Maria Zuber will serve as the external co-chairs of the President’s Council of Advisors on Science and Technology.

The Senate Commerce, Science and Transportation Committee is expected to hold Pete Buttigieg's nomination hearing for transportation secretary on Thursday at 10 a.m.

Others expected for next week: Avril Haines to serve as director of national intelligence, Janet Yellen to serve as treasury secretary, Tony Blinken to serve as secretary of state, Lloyd Austin to serve as secretary of defense, and Alejandro Mayorkas to serve as Department of Homeland Security secretary.

The nomination hearing for Avril Haines, Biden’s pick for director of national intelligence, is now scheduled for Tuesday, the Senate Intelligence Committee announced. The hearing is slated to start at 10 a.m. ET.

It was originally scheduled for Friday but was then postponed.

After the House Reading Clerk concluded reading the full impeachment resolution against President Trump, the House has proceeded with the session by kicking off two hours of debate on the article on impeachment charging Trump with inciting an insurrection. House Speaker Nancy Pelosi was the first to deliver remarks and called Trump “a clear and present danger” to the country.

"The president of the United States incited this insurrection, this armed rebellion, against our common country. He must go. He is a clear and present danger to the nation that we all love," Pelosi said. "Since the presidential election in November, an election the president lost, he has repeatedly lied about the outcome, sowed self-serving doubt about democracy and unconstitutionally sought to influence state officials to repeal reality."

"My fellow members, my fellow Americans, we cannot escape history. Let us embrace our duty, fulfill our oath, and honor the trust of our nation. And we pray that God will continue to bless America," she added, calling on the House to vote to impeach Trump and for the Senate to vote to convict him.

A spokesperson for Pelosi confirmed to ABC News she is wearing same outfit Wednesday that she wore for Trump's last impeachment vote on Dec. 18, 2019.
