LONDON — For Britain, it has been a year of agonizing numbers.

Since Prime Minister Boris Johnson plunged the country into lockdown on March 23, 2020, to slow the spread of the coronavirus, the U.K. has seen its highest surge in deaths since World War II and its deepest economic slump in 300 years. On a more positive note, Britain is now rolling out its fastest vaccination campaign on record.
