New data in a real-world setting shows that two of the vaccines for COVID-19 authorized in the United States not only prevent severe illness and hospitalization from the coronavirus but also infection.

The results of a new study from the Centers for Disease Control and Prevention show that the Pfizer-BioNTech and Moderna vaccines are 90% effective at preventing both symptomatic and asymptomatic COVID-19 infections for those who are fully vaccinated. They are 80% effective for those who have received one dose.
