Boris Johnson has urged people to come forward to get a Covid booster jab, as the latest data suggests the Omicron variant of the virus may be milder than others.

The British prime minister used his Christmas message to tell people to get the “wonderful” gift of a booster jab as part of the “neighbourly” spirit of the season.
