Pfizer CEO Albert Bourla said on Tuesday that, at some point in the future, a strain of COVID-19 that is resistant to vaccines is likely to emerge.
“Every time that the variant appears in the world, our scientists are getting their hands around it,” Bourla told Fox News in an interview. “They are researching to see if this variant can escape the protection of our vaccine. We haven’t identified any yet but we believe that it is likely that one day, one of them will emerge.”
