"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 dynamics of the outbreak, that very likely will not be until the second or third quarter of the year."
