Speaking by video-conference to deputies from the European Parliament's health committee, Tedros Adhanom Ghebreyesus said that if such a vaccine became a reality, it should become a public good available to all.
"It would be very difficult to say for sure that we will have a vaccine," Tedros said. "We never had a vaccine for a coronavirus. So this will be, when discovered, hoping that it will be discovered, it will be the first one," he said.
He said the WHO had already more than a 100 candidates for a vaccine of which one was at an advanced stage of development."Hoping that there will be a vaccine, the estimate is we may have a vaccine within one year. If accelerated, it could be even less than that, but by a couple of months. That's what scientists are saying," he said.
