Fauci, who is director of the National Institute of Allergies and Infectious Diseases (NIAID), told the U.K.'s Guardian newspaper in an interview published on Monday that vaccinations were key to controlling the virus. "We don't want to declare victory prematurely because we still have a ways to go," Fauci said. "But the more and more people that can get vaccinated, as a community, the community will be safer and safer." "As long as there is some degree of activity throughout the world, there's always a danger of variants emerging and diminishing somewhat the effectiveness of our vaccines," Fauci said.
