CDC: Vaccinated People Reduce Risk of COVID-19 Mortality by More Than 10 Times

In a large study looking at incidence rates for hospitalization and mortality, results changed relatively little in terms of vaccine effectiveness, even after the Delta variant became the dominant strain.

The Centers for Disease Control and Prevention (CDC) reported its study finding that COVID-19 vaccination continued to be highly effective against hospitalization and mortality rates, even with the emergence of the Delta variant becoming the dominant strain.

“Getting vaccinated protects against severe illness from COVID-19, including the Delta variant, and monitoring COVID-19 incidence by vaccination status might provide early signals of changes in vaccine-related protection that can be confirmed through well-controlled vaccine effectiveness (VE) studies,” The CDC report stated.

The study was conducted across 13 jurisdictions from April 4-July 17, 2021.

In people unvaccinated, they were 5 times more likely to become infected, 10 times more likely to be hospitalized, and over 10 times more likely to die from COVID-19.

“During April 4–July 17, a total of 569,142 (92%) COVID-19 cases, 34,972 (92%) hospitalizations, and 6,132 (91%) COVID-19–associated deaths were reported among persons not fully vaccinated, and 46,312 (8%) cases, 2,976 (8%) hospitalizations, and 616 (9%) deaths were reported among fully vaccinated persons in the 13 jurisdictions,” the investigators wrote.
