'The most dangerous time': UK sees toughest virus threat yet

LONDON: The United Kingdom opened seven mass vaccination centers on Monday as it moved into the most perilous moment of the Covid-19 pandemic, with exhausted medical staff reeling under the pressure of packed hospitals and increasing admissions.

England's chief medical officer, Dr. Chris Whitty, warned people to strictly follow measures to prevent the spread of the virus while they wait their turn for a vaccine shot. The government is trying to vaccinate some 15 million people by Feb. 15 — but Britain's National Health Service is struggling to treat those who are ill now.
