Anthony Fauci

The WHO declared a pandemic. The NBA shut down its season. President Trump banned travel from Europe. Tom Hanks tested positive. On one day a year ago, the coronavirus became very real in America.

NIAID Director Anthony Fauci sheds light on vaccines, variants, and a return to normalcy.

The administration is in its early days, but the infectious disease expert says he's encouraged by the new president's attitude about the pandemic. Science, Fauci says, is "going to rule."

The devastating news comes almost one year to the day after the first case of the virus was detected in the country and as officials warn that the situation will only grow worse before it gets better.

Dr. Anthony Fauci and former President Trump butted heads, leading to a public rift between the pair. Fauci says he now feels free to "let the science speak."

Gov. Gavin Newsom made the announcement during an online conversation about the pandemic with Dr. Anthony Fauci, but he offered little additional information about the circumstances of the diagnosis.

In a virtual town hall for kids on CNN, Dr. Anthony Fauci said he made a trip to the North Pole to get Santa vaccinated for COVID-19. "He is good to go."

The Food and Drug Administration greenlights the biotech firm's vaccine for emergency use in the U.S. The move bolsters a vast inoculation effort that's already underway.

Dr. Fauci said once the vaccine becomes widely available, if by "April, May, June, July, we get as many people vaccinated as possible, we could really turn this thing around" by the end of 2021.

The president-elect also told CNN on Thursday he would ask Americans to wear masks for the first 100 days of his administration.

More than 91,000 people were hospitalized with the coronavirus on Saturday — over 6,000 of them on ventilators. With the holiday season fast approaching, health experts fear the worst is yet to come.

At StoryCorps, Anthony Fauci talks with wife, Christine Grady, about parenting, running and work. He sees a link: "the idea of sticking with something and not giving up, even when it's painful."
