Fauci said the US's COVID-19 vaccines are powerful enough that they should be able to shoulder new strains of the infection with limited impact on efficacy

Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, prepares to receive his first dose of a COVID-19 vaccine at the National Institutes of Health on December 22, 2020 in Bethesda, Maryland.

Top US infectious disease expert Dr. Anthony Fauci said Thursday the COVID-19 vaccines might not be as effective against new coronavirus strains, but that the vaccines were powerful enough that they would still be beneficial. 

Fauci, director of the National Institute of Allergy and Infectious Diseases and an advisor on the White House coronavirus task force, relayed new data findings during a press conference at the White House Thursday.

Several new coronavirus strains have been detected in various countries - including the UK and South Africa - raising questions on how newly developed vaccines being distributed nationwide will factor into it. Fauci said both vaccines from Pfizer and Moderna have proven to be highly effective - providing a "cushion effect" in that the new strains could only "somewhat" diminish its efficacy.

"We're following very carefully the one in South Africa, which is a little bit more concerning, but nonetheless not something that we don't think we can handle," Fauci said during the press conference. The US has not yet reported any cases of the coronavirus strain from South Africa, but infections from the UK strain have emerged.

The infectious disease expert said the emergence of new strains only further emphasizes the importance of getting vaccinated against COVID-19 and continue to build herd immunity against the virus. The spread of the new strains, which could be mutations of the coronavirus that causes COVID-19, can be suppressed if more people are immunized.

"Bottom line: We're paying very close attention to it," Fauci said. "There are alternative plans if we ever have to modify the vaccine. That's not something that is a very onerous thing, we can do that given the platforms we have."

Fauci also stressed that it's common for coronaviruses to mutate.

"Most of the mutations don't have any physiological relevance with regard to the function of the virus itself.  However, every once in a while, you get mutations, either singly or clustered in combinations, which do have an impact," he said.

Dr. Rochelle Walensky, the new director for the Centers for Disease Control and Prevention appointed by President Joe Biden, echoed Fauci's sentiment on the efficacy of COVID-19 vaccines on new variants. In an interview with the JAMA Network on Tuesday, Walensky said she remains "optimistic" about the vaccines suppressing the spread of new strains.

"I'm really optimistic about how these variants are going to go," Walensky said. "I could be wrong. It could be that we'll find variants and variants may emerge ... where the vaccine is less potent, but I'm still currently optimistic."
