People who are not fully vaccinated are over 10 times more likely to be hospitalized with COVID-19 and 11 times more likely to die from the virus, a new Centers for Disease Control and Prevention study found.

The study released Friday looked at over 600,000 COVID cases, hospitalizations and deaths in 13 states from April through mid-July and found “further evidence of the power of vaccination,” CDC Director Rochelle Walensky said at a White House briefing.

The study also found that unvaccinated people are over four times more likely to be infected with COVID.

“The bottom line is this: We have the scientific tools we need to turn the corner on this pandemic," Walensky said. “Vaccination works and will protect us from the severe complications of COVID-19.”

The CDC also conducted a second study that found that the Moderna vaccine was slightly more effective (95%) in preventing hospitalizations compared to Pfizer-BioNTech (80%) and Johnson & Johnson (60%).

Despite this study confirming Moderna’s effectiveness, public health officials have been encouraging people to get whatever vaccine is available, reinforcing that all three vaccines provide strong protection against severe symptoms and death.

This newly released study comes the day after President Joe Biden announced two sweeping executive orders that would require about two-thirds of the country’s workforce to get vaccinated.

“We still have nearly 80 million Americans who have failed to get the shot,” Biden said. "We've been patient, but our patience is wearing thin, and your refusal has cost all of us.”

Currently, 63% of the U.S. population has received at least one dose of the vaccine while 53% are fully vaccinated.
