On Friday afternoon, President-Elect Joe Biden shared a detailed plan to tackle the COVID-19 vaccination rollout, promising to fight the pandemic with "the full strength of the federal government."

In a speech in Delaware, Biden laid out his five-part plan for how to speed up the vaccination campaign: Open up vaccine eligibility to more people; create more vaccination sites; increase vaccine supply; hire a vaccination workforce; and launch a large-scale public education campaign.

The Trump administration is making several big changes to its COVID-19 vaccine distribution strategy, officials announced Tuesday, in a bid to jump-start the rollout and get more Americans vaccinated quickly.

The first change is to call on states to expand immediately the pool of people eligible to receive vaccines to those 65 and older, and those with underlying health conditions that make them more susceptible to COVID-19.

This time last year, the world was heading into a pandemic that would upend everything and cost 1.9 million lives — and counting. The promise of the new year is that vaccines are finally here and offer a way out.

People who are ages 75 and older or frontline essential workers should be next in line to get a COVID-19 vaccine, a federal advisory committee to the Centers for Disease Control and Prevention determined Sunday.

Those groups follow frontline health care workers and nursing home residents, who have already begun receiving the limited supplies of vaccines available.

An important federal advisory committee at the Centers for Disease Control and Prevention has added its vote of support for the Pfizer-BioNTech COVID-19 vaccine.

In an emergency meeting Saturday, the CDC's Advisory Committee on Immunization Practices voted to recommend the first COVID-19 vaccine for use for people 16 or older in the U.S, expressing hope that the vaccine would help curb the spread of the disease that has killed more than 295,000 people in the U.S.

A federal advisory committee to the Centers for Disease Control and Prevention voted Tuesday to recommend who should get COVID-19 vaccines first once one is authorized for use.

Health care workers are expected to be first in line to be offered a COVID-19 vaccine when one is available.

It makes sense: Getting a safe, effective vaccine would help keep them and their patients healthy. Seeing doctors, nurses and medical aides getting COVID-19 vaccines would also set an example for the community.

Top officials from Operation Warp Speed, the government's program to fast-track the development and delivery of COVID-19 vaccines, announced they've allocated 6.4 million doses of COVID-19 vaccines to states based on their total populations.

A top U.S. Army general who is co-leading the federal COVID-19 vaccine initiative anticipates that the first of millions of Americans could start receiving COVID-19 vaccines as soon as next month.

Health care workers will almost certainly get the first doses of COVID-19 vaccine in the U.S. when one is approved, according to Dr. José Romero, head of the committee that develops evidence-based immunization guidelines for the Centers for Disease Control and Prevention.

States should be working toward being ready to give out COVID-19 vaccines by Nov. 15, according to a target date made public by the Centers for Disease Control and Prevention on Friday.

As coronavirus cases rise swiftly around the country, surpassing both the spring and summer surges, health officials brace for a coming wave of hospitalizations and deaths. Knowing which hospitals in which communities are reaching capacity could be key to an effective response to the growing crisis. That information is gathered by the federal government — but not shared openly with the public.

Dr. William Foege doesn't know how his private letter to the director of the Centers for Disease Control and Prevention, Robert Redfield, got leaked — but he stands by its contents.

"I think we've got about the worst response to this pandemic that you could possibly have," said Foege, who served as CDC director from 1977 to 1983, spanning the Carter and Reagan administrations, in an interview with NPR.

The federal government is starting to crack down on the nation's hospitals for not reporting complete COVID-19 data into a federal data collection system.

Last Thursday afternoon, when Hope Hicks tested positive for the coronavirus, President Trump was aboard Marine One, on his way to a campaign fundraiser at his New Jersey golf club.

Several members of Congress and cabinet members who've spent time with President Trump in the last week were tested for coronavirus — and have announced the result was negative.

But that doesn't mean they're in the clear.

These results could be a false negative — which are common in people who've been infected with the virus during the first few days after exposure.

Updated Friday 2:15 p.m. ET to include a comment from the Centers for Medicare & Medicaid Services.

The federal government is preparing to crack down aggressively on hospitals for not reporting complete COVID-19 data daily into a federal data system, according to internal documents obtained by NPR.

It's still unknown when a COVID-19 vaccine might be available in the United States. But when one is first approved, there may only be 10 million to 15 million doses available, which may be enough to cover around 3% to 5% of the U.S. population.
