Microsoft co-founder Bill Gates said Wednesday that people could need multiple doses of a potential coronavirus vaccine to immunize themselves from the coronavirus. If necessary, the multiple doses could require more than 7 billion vaccinations to be administered worldwide.
“None of the vaccines at this point appear like they’ll work with a single dose,” Gates said. “That was the hope at the very beginning.”
The billionaire philanthropist, who has donated $300 million towards the global effort to combat COVID-19 through the Bill & Melinda Gates Foundation, told “CBS Evening News” anchor and managing editor Norah O’Donnell that deploying a coronavirus vaccine will require a global effort.
