An effective coronavirus vaccine could require multiple doses, Microsoft co-founder Bill Gates said on Wednesday.
“None of the vaccines at this point appear like they’ll work with a single dose,” Gates told CBS News. “That was the hope at the very beginning.”
The Bill & Melinda Gates Foundation has committed more than $250 million to fight COVID-19. The charitable foundation boosted the contribution after Gates criticized President Trump’s decision to halt funding to the World Health Organization (WHO).
Gates told CBS News that a coronavirus vaccine requires a global effort.
