LONDON: England's health service said it will expand its COVID-19 booster vaccination programme to include 16- and 17-year-olds from Monday.

Until now, booster jabs have been limited to 16- and 17-year-olds most at risk from the coronavirus.

"More than four in five adults in England have already been boosted, helping to protect them from severe illness," British health minister Sajid Javid said in a statement.

"We're now extending the programme to 16- and 17-year-olds so they can top-up their immunity this winter to keep themselves and their friends safe."
