FRIDAY November 5, 2021 (HealthDay News) – The risk of serious illness or death is lower in vaccinated people who contract major infections with COVID-19 than in unvaccinated people who are infected, two new studies confirm.

An ongoing study of 780,000 US veterans has found that the three vaccines available in the US offer strong protection against serious illness and death, despite a significant decline in their effectiveness against mild and asymptomatic infections. CNN reported.

“Although breakthrough infection increased the risk of death, vaccination remained protective against death in people who were infected during the Delta wave,” the researchers wrote in the study published Nov. 4 in the newspaper. Science.

“Our analysis by vaccine type, including Pfizer-BioNTech, Moderna and [Johnson & Johnson’s] The Janssen vaccines suggest a decrease in the effectiveness of the vaccine against infection over time, particularly for the Janssen vaccine, ”the researchers said. fully vaccinated people had a much lower risk of death after infection. “

The second study found that unvaccinated infected people were much more likely to end up in hospital on a ventilator or die than people who had breakthrough infections after being fully vaccinated with the Pfizer or Moderna vaccines.

Researchers analyzed data from more than 4,500 patients admitted to 21 U.S. hospitals with respiratory illnesses between March and July and found that unvaccinated patients accounted for 84.2% of COVID-19 hospitalizations, 91% of COVID-deaths. 19 and nearly 94% of those who either needed a ventilator or died, CNN reported.

The study was published on November 4 in the Journal of the American Medical Association.

“We are now very confident that the vaccine will still help you, even if you get COVID,” said study team leader Dr. Wesley Self, associate professor at Vanderbilt University. CNN. “Even those who get sick don’t get as sick as if they weren’t vaccinated.”
