Dr Anthony Fauci cautioned that early COVID-19 vaccines are aimed at preventing symptoms during Yahoo Finance's All Markets Summit on Monday 'If the vaccine allows you to prevent initial infection, that would be great,' he said. '[But] the primary endpoint [is] to prevent clinically recognizable disease' At least four vaccine candidates are currently in late-stage clinical trials Fauci has said he is cautiously optimistic that a vaccine will arrive by year end But he warned that early vaccines may only be 50 to 60 percent effective
