Booster doses of vaccine have helped increase the level of Covid-19 antibodies among people in older age groups in the UK, new analysis suggests.

Some 95.8% of over-80s in England were likely to have tested positive for antibodies in the week to November 7, up from 87.9% a month earlier, with 75-79 year-olds seeing a jump from 86.9% to 95.8% in the same period.
