Even as movie theaters, gyms and salons are opening and some states are allowing limited indoor dining, daily life in the U.S. won't get back to normal until late 2021 when a vaccine for Covid-19 could be widely distributed, the nation's leading infectious disease expert, Dr. Anthony Fauci, said Friday.

In an interview on MSNBC's "Andrea Mitchell Reports," Fauci, who is the director of the National Institute for Allergy and Infectious Diseases, said he remains confident there will be a vaccine available by the end of this year or early 2021.
