The World Economic Forum will defer its annual meeting in Switzerland's Davos because of continuing uncertainty over the spread of the Omicron coronavirus variant.

On Jan. 23, 2020, the day the novel coronavirus forced the Chinese city of Wuhan into lockdown, two American doctors named Seth Berkley and Richard Hatchett met at the bar of the Hard Rock Hotel in Davos, Switzerland, to talk about vaccines.

The World Economic Forum said Wednesday that its annual meeting, which has already been postponed and moved from Switzerland to Singapore, will be pushed back again due to pandemic-related challenges.
