The Government's vaccine advisers have advised that all adults in the UK should be given a booster jab of the coronavirus vaccine to combat the new Omicron variant.

The measures also include:

• Shortening the gap between a second jab and a booster from six months to three months

• Giving a second jab to children aged between 12 and 15 years old - again after no less than three months

• Severely immunosuppressed people given access to another booster - meaning for some, a fourth dose this winter
