Vaccine verdict due by early December: Fauci

LONDON

: US infectious disease expert

Anthony Fauci

said on Sunday it would be clear whether a

Covid-19 vaccine

was safe and

effective

by early December, but that more widespread vaccination would not be likely until later in 2021.


“We will know whether a vaccine is safe and effective by the end of November, the beginning of December,” Fauci told the BBC. “When you talk about vaccinating a substantial proportion of the population, so that you can have a significant impact on the outbreak, that very likely will not be until the second or third quarter of the year.”
