When asked, Murthy said the U.S. still needs more data on the U.K. variant before making the same determination.Preliminary analysis of the mutated strain, which was first identified in the U.K., suggests it may be the culprit behind Britain’s spike in cases. Johnson has previously said that the new variant could also be as much as 70% more transmissible. The British government has also confirmed that another infectious variant of the coronavirus identified in South Africa has emerged in the United Kingdom.Read more: 5 things to know about the new Covid strain spreading in the UKLast month, Colorado announced the nation’s first case of the new and potentially more infectious strain of Covid-19. The Centers for Disease Control and Prevention warned last week that the U.K. variant, which is already circulating in at least 10 states, could become the dominant variant in the U.S. by March.Dr. Anthony Fauci, Biden’s top Covid-19 medical adviser, said last week that the Covid-19 vaccines currently on the market may not be as effective against new strains of the coronavirus.Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, speaks during a news conference in the White House in Washington, D.C., U.S., on Thursday, Nov. 19, 2020.Chris Kleponis | Bloomberg | Getty Images”Bottom line: We’re paying very close attention to it,” Fauci said of the known variants identified in the U.K., South Africa and Brazil.”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,” he told reporters during a White House press briefing.
