The vaccines that the world’s leading pharmaceutical firms have developed to prevent COVID-19 work really well. Against the novel coronavirus, that is.
But SARS-CoV-2 isn’t the only coronavirus out there; there are more pathogens like the one that causes COVID-19. And it may be only a matter of time before some new coronavirus jumps from whatever animal population harbors it to human beings. When it does, it could wreak as much havoc as SARS-CoV-2, if not more. That’s what worries a team of scientists led by Barton Haynes and Kevin Saunders at Duke University. And what motivated them, a year ago, to begin work on a new vaccine that could work against a whole bunch of coronaviruses.
