An analysis of more than 50,000 Covid-19 deaths in England this year offers reassuring evidence on the effectiveness of vaccines, showing that mortality rates among people fully inoculated against coronavirus were a fraction of those without a shot.
The study, by the U.K.’s Office for National Statistics, recorded 640 deaths among fully vaccinated individuals between Jan. 2 and July 2, or 1.2% of 51,281 Covid-19 deaths overall.
The average age of the people in those breakthrough deaths was 84, the ONS said, two years older than the average for all Covid-19 deaths.
An analysis of data from nine states by the Centers for Disease Control and Prevention published Friday found vaccines reduce the risk of hospitalization with Covid-19 by 81% to 89%. An analysis from Germany published Thursday showed vaccines reduced the risk of hospitalization in those 60 years and older by 94% and the risk of death by 91%. The U.K.’s Public Health England estimates vaccination has prevented more than 100,000 deaths in England.
In the U.S., federal data shows working-age adults account for a growing share of Covid-19 deaths because they are less likely to be vaccinated than older people.
