Did vaccines make a difference? Study looks at rates of severe illness from COVID-19 – CTV

A new study has added to a growing body of evidence that COVID-19 vaccines and boosters protect against severe illness and death.

Published in the Journal of the American Medical Association, the peer-reviewed study followed more than 1.6 million U.S. patients over 11 months, and found that among those who were vaccinated and boosted, the incidence of death or hospitalization for COVID-19 pneumonia was only 8.9 per 10,000 persons. According to the study, severe outcomes like these occurred almost exclusively among high-risk patients like older adults, the immunocompromised and those with conditions like diabetes and high blood pressure.
