WHO director says the world 'cannot go back to the way things were,' even if a vaccine is found

• WHO Director-General Tedros Adhanom Ghebreyesus

Even if we do have a vaccine, it wouldn't end the pandemic on its own.

"At the same time, we will not, we cannot, go back to the way things were," he continued.

"Throughout history, outbreaks and pandemics have changed economies and societies, this one will be no different," Tedros added.

"In particular, the pandemic has given new impetus to the need to accelerate efforts to respond to climate change," he said. "The pandemic has given us a glimpse of our world as it could be, cleaner skies and rivers."
