CDC Finds mRNA Vaccines Reduce COVID-19-Related Hospitalizations Among Older Adults

The U.S. Centers for Disease Control and Prevention (CDC) this week released an assessment finding that fully vaccinated adults from the Pfizer-BioNTech and Moderna mRNA vaccines 65 years of age and older were 94 percent less likely to be hospitalized with COVID-19 than people of the same age who were not vaccinated. People 65 and older who were partially vaccinated were 64 percent less likely to be hospitalized with COVID-19 than people who were not vaccinated.

The CDC indicates these findings are the first real-world results in the U.S. confirming clinical trial data showing mRNA vaccines prevent severe COVID-19 illness. The findings additionally support the CDC’s recommendation for COVID-19 vaccination among people 65 and older in the U.S. population. The CDC’s assessment explored hospitalizations in two U.S. hospital networks covering 24 hospitals in 14 states. Vaccine effectiveness was assessed by comparing the odds of COVID-19 vaccination among hospitalized people who tested positive for the virus that causes COVID-19 versus those who tested negative.
