The omicron variant has seen Covid-19 cases spike around the UK, and NHS national medical director Professor Stephen Powis said the NHS is "on a war footing" as staff battle the virus.
“We are once again ramping up to deal with the rise in covid infections, and quite rightly staff are making every possible preparation for the uncertain challenges of omicron," he said.
"It remains the case that the best way to protect yourself and others is to follow guidance and to come forward and get your first, second and booster jabs.”
