New Studies Show Unvaccinated Are 11 Times More Likely to Die of COVID-19

New U.S. studies released Friday show that COVID-19 vaccines provide strong protection against hospitalizations and death, even in cases involving the highly contagious delta variant.

One study, which followed 600,000 people from April through mid-July, found that people who were not vaccinated were more than 10 times more likely to be hospitalized and 11 times more likely to die than those who were fully vaccinated. The unvaccinated were 4.5 times more likely to get infected, according to the study released Friday by the U.S. Centers for Disease Control and Prevention. The CDC also released two other studies that show vaccine protection appearing to wane in older populations, particularly those 75 and older.
