A new study shows the persistent syndrome of Covid-19 after-effects known as long Covid can develop after “breakthrough” infections in vaccinated people.

A study out of Oxford University’s Leverhulme Centre for Demographic Science found that the Covid-19 pandemic has resulted in the largest drop in life expectancy in western Europe since World War II.

The Covid-19 pandemic reduced life expectancy in 2020 by the largest amount since World War Two, according to a study published on Sept. 27 by Oxford University, with the life expectancy of American men dropping by more than two years.

A study published in The Lancet Infectious Diseases found that the Pfizer-BioNTech, Oxford-AstraZeneca or Moderna vaccines resulted in a drop in “long-haul” Covid-19 by 50 percent.
