Boris Johnson delays end of England’s coronavirus restrictions as delta variant cases climb

The idea behind the delay, Johnson said Monday, is to get more people vaccinated, especially with their second dose, before all restrictions are lifted. Recent studies indicate that after a first dose of the Oxford-AstraZeneca or Pfizer-BioNTech coronavirus vaccine, people are only about 33 percent protected from the delta variant, but that increases to more than 80 percent with the second dose.
