The leading U.S. infectious disease specialist, Dr. Anthony Fauci, said on Wednesday he foresees America achieving enough collective Covid-19 immunity through vaccinations to regain “some semblance of normality” by autumn 2021, despite early setbacks in the vaccine rollout.
Fauci made his remarks during an online discussion of the pandemic with California Governor Gavin Newsom, who announced at the outset that a more infectious coronavirus variant originally found in Britain has been detected in his state, a day after the first known US case was documented in Colorado.
Newsom said the coronavirus variant B.1.1.7 had been confirmed earlier in the day in a Southern California patient. He did not provide further details. But the California Department of Public Health said in statement later that the person, a San Diego County patient, has no known travel history, suggesting the variant is spreading within the community.
Fauci said he was “not surprised,” adding that additional cases of the variant would likely surface around the country and that the mutating nature of such viruses is normal.
“It appears that this particular mutation does make the virus better at transmitting from one person to another,” he said. However, individuals infected with earlier forms of SARS-CoV-2 “don’t seem to get re-infected by this,” meaning that any immunity already acquired “is protective against this particular strain,” Fauci added.
