The Food and Drug Administration has endorsed Johnson & Johnson's single-dose COVID-19 vaccine for emergency use authorization. If approved, it will join the two-dose vaccines from Pfizer and Moderna currently on the market. In a new video update, Dartmouth-Hitchcock Medical Center (DHMC) Chief Quality Officer Michael S. Calderwood, MD, MPH, shares information about the efficacy of J&J's vaccine, its potential impact on the trajectory of the pandemic, and why you should feel safe and comfortable taking whichever manufacturer's vaccine becomes available to you first.

“The effectiveness of the Johnson & Johnson vaccine is actually 85 percent in the United States, South Africa and Brazil, including where they have some of these virus variants that have raised concern about lower efficacy of other vaccines,” Calderwood said. “In terms of preventing severe illness or even death, this Johnson & Johnson vaccine is extremely effective, and it is effective against some variants that weren’t studied when Moderna and Pfizer were doing their trials.”
