Dr. Anthony Fauci On New COVID-19 Omicron Variant: ‘Do Not Pull Back On Your Guard’

Today: November 27, 2021

Dr. Anthony Fauci, the director of the National Institute of Allergy and Infectious Diseases and chief medical adviser to the president, joins Weekend TODAY to discuss the omicron variant and whether Americans should be concerned about the newly discovered COVID-19 strain.

"We have not detected it yet, but when you have a virus that is showing this degree of transmissibility and you're already having travel-related cases that they've been noted in Israel and Belgium and in other places — when you have a virus like this, it almost invariably is ultimately going to go essentially all over,” Fauci told "Weekend TODAY" on Saturday.
