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.

-Dr. Francis Collins will continue serving in his role as director of the National Institutes of Health.

-Kei Koizumi will serve as OSTP chief of staff and is one of the nation’s leading experts on the federal science budget.

-Narda Jones will serve as OSTP legislative affairs director.

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.

This is the sixth Cabinet-level nomination hearing to be noticed. 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.

When he leaves for Alamo, Texas, Tuesday morning, it will be President Trump's first time in public since last Wednesday -- the day his supporters stormed the U.S. Capitol after he encouraged a crowd of thousands, at a rally beforehand, to put pressure on lawmakers affirming Biden's victory in Congress.

Apart from posting video on Twitter last Thursday, before the platform permanently suspended his account, the president has remained behind closed doors at the White House -- spending his final days in office out of the public eye -- but is expected to break his silence with afternoon remarks.

"President Trump is expected to travel to Alamo, Texas, on Tuesday to mark the completion of more than 400 miles of border wall -- a promise made, promise kept -- and his administration's efforts to reform our broken immigration system," White House deputy press secretary Judd Deere told reporters ahead of the visit.

The president is facing renewed calls from congressional Democrats to be removed from office in the wake of last week's riot, with the House poised to pass an impeachment resolution as early as Wednesday charging the president with incitement of insurrection -- and setting Trump up to be the first president in history to be impeached twice.

Trump, for the first time since the assault, spoke with Vice President Mike Pence at the urging of his advisers and allies in an Oval Office meeting Monday that lasted 90 minutes and was friendly in nature, according to White House officials briefed on the meeting. Pence is not expected to invoke the 25th Amendment as House Speaker Nancy Pelosi has called on him to do.

Biden, on Tuesday, will receive the President’s Daily Brief and meet with advisers, while his transition team and allies in Congress begin a push to confirm his national security nominees so they're in place next week, with priority on the confirmation of Department of Homeland Security Secretary-designate Alejandro Mayorkas.

Defense Secretary-designate Gen. Lloyd Austin, nominee for Director of National Intelligence Avril Haines and Secretary of State-designate Tony Blinken will also be part of the push ahead of their hearings on Capitol Hill.

Biden’s nominees may also need now to contend with an impeachment trial in the Senate. Biden suggested in remarks Monday the Senate look into splitting the its time in order to confirm his nominees, pass COVID-19 relief and deal with a presidential impeachment.
