Unvaxxed 11 times more likely to die: CDC


People who weren't fully vaccinated this spring and summer were more than 10 times more likely to be hospitaliz­ed, and 11 times more likely to die of COVID-19 than those who were fully vaccinated, according to one of three major studies published Friday by the U.S. Centers for Disease Control and Prevention that highlight the continued efficacy of the three vaccines available in the States amid the spread of the highly contagious Delta variant.

A second study showed the Moderna vaccine was moderately more effective in preventing hospitaliz­ations than its counterpar­ts from Pfizer-biontech and Johnson & Johnson.

That assessment was based on the largest U.S. study to date of the real-world effectiven­ess of all three vaccines, involving about 32,000 patients seen in hospitals, emergency department­s and urgent care clinics across nine states from June through early August.

While the three vaccines were collective­ly 86% effective in preventing hospitaliz­ation, protection was significan­tly higher among Moderna vaccine recipients (95%) than among those who got Pfizerbion­tech (80%) or Johnson & Johnson (60%).

That finding echoes a smaller study by the Mayo Clinic Health System in August, not yet peer-reviewed, which also showed the Moderna vaccine with higher effectiven­ess than Pfizer-biontech at preventing infections during the Delta wave.
