- More than 600,000 Covid cases from April through mid-July were analyzed and linked to vaccination status.
- Those who were unvaccinated were about 4.5 times more likely to contract the virus, more than 10 times more likely to be hospitalized with the virus, and 11 times more likely to die from the disease.
- About 54% of the U.S. population is fully vaccinated, according to the CDC.

Unvaccinated people are 11 times more likely than vaccinated people to die from Covid-19, a large study by the Centers for Disease Control and Prevention found.
The study looked at Covid-19 cases, hospitalizations and deaths in 13 states "and found further evidence of the power of vaccination," CDC Director Dr. Rochelle Walensky said in a briefing Friday.
