“You have to do it by reaching out to the community, not by a Washington saying,” added Fauci, a member of the White House Pandemic Task Force.
Fauci is the director of the National Institute of Allergy and Infectious Diseases, which is working with Moderna on a vaccine.
The Cambridge, Massachusetts-based drugmaker began the latest round of clinical trials on Monday, making it the first candidate to enter a crucial research milestone in the United States.
The company’s Phase 3 trial will test its experimental inoculation in approximately 30,000 people at nearly 100 research sites across the country to assess whether it can safely and effectively prevent COVID-19 infections.
Fauci called it “the critical time” for vaccine development, adding that he was “cautiously optimistic” about progress.
“We’re trying to figure out if it actually works,” he told CNN.
It will take “several months to determine if in fact (the vaccine) is working,” Fauci added. “Going from not even knowing what the virus was in early January to a Phase 3 trial is really record time.”
Meanwhile, the doctor also told CNN he may have been exposed to the virus.
He said he was in the same room as National Security Advisor Robert O’Brien “a week or two ago”.
O’Brien, who tested positive for the disease, said he was exhibiting “mild symptoms” and “isolating himself” while working from home.
