British Prime Minister Boris Johnson will call on fellow leaders of the Group of Seven (G7) nations to make a commitment to vaccinate the world's population against coronavirus by the end of 2022.
Britain will host the first in-person summit of G7 leaders in almost two years.
Johnson said he would seek a pledge to hit the global vaccination goal.
He further said that 'vaccinating the world by the end of next year would be the single greatest feat in medical history'.
