WASHINGTON, DC — Of the three COVID-19 vaccines available in the United States, the Moderna vaccine is most effective in preventing hospitalization, according to a newly released Centers for Disease Control and Prevention study.

The study, released Thursday, found the Moderna vaccine is 93 percent effective in preventing hospitalization. The Pfizer-BioNTech and Johnson & Johnson vaccines were 88 percent and 71 percent, respectively.

The study was comprised of more than 3,600 adults who were hospitalized at 21 U.S. hospitals across 18 states between March 11 and Aug. 15. It also found that vaccine effectiveness in Moderna recipients dropped to 92 percent after 4 months. Meanwhile, Pfizer's effectiveness fell to 77 percent.
