British Prime Minister Boris Johnson said on Monday he could not promise there would be successful vaccine against COVID-19 developed by the end of this year, saying "we're not there yet" even as Britain lines up supplies.
"To say that I'm 100% confident that we'll get a vaccine, this year or indeed next year, is alas, just an exaggeration. We're not there yet," Johnson said after Britain announced supply deals for two more vaccines under development.
