LONDON — News from global pharma firms that their coronavirus vaccine candidates are highly effective is welcome, but work needs to be done to ensure they reach everyone around the world, the World Health Organization's Europe chief said Thursday.

"I firmly believe that there is more hope ahead of us than despair behind us," Dr. Hans Kluge, WHO regional director for Europe, said in an online broadcast as he discussed the latest vaccine news. He added that it would not be a "silver bullet" as access to the vaccine would be limited at first.
