More than 500,000 people have died from COVID-19 in the U.S.

This week President Biden is asking Americans to mark the 500,000 deaths with a moment of silence at sunset Monday. He's also ordered flags on all federal buildings lowered to half-staff for five days.

COVID-19 vaccines are scarce. Many people who want the shots can't get them yet, either because they're not yet eligible, according to priorities set by their state or county, or because there aren't any available appointments.

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.

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.

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.
