The World Health Organization said Friday that a vaccine will be a “vital tool” in the global fight against the coronavirus, but it won’t end the Covid-19 pandemic on its own and there’s no guarantee scientists will find one. 

World leaders and the public must learn to manage the virus and make permanent adjustments to their daily lives to bring the virus down to low levels, WHO Director-General Tedros Adhanom Ghebreyesus said during a press conference from the agency’s Geneva headquarters. “At the same time, we will not, we cannot go back to the way things were.”

Throughout history, outbreaks and pandemics have changed economies and societies, he said.

“In particular, the Covid-19 pandemic has given new impetus to the need to accelerate efforts to respond to climate change,” he said. “The Covid-19 pandemic has given us a glimpse of our world as it could be: cleaner skies and rivers.”

The virus has infected more than 22.7 million people worldwide and killed at least 794,100 in more than seven months, according to data compiled by Johns Hopkins University. There are at least 30 potential vaccines currently in clinical trials, according to the WHO, but there is no guarantee they will be safe and effective, he said.
