A panel of medical experts recommended that the Food and Drug Administration approve Johnson & Johnson’s coronavirus vaccine for use in the U.S.
If approved by the FDA as expected, this would be the third vaccine, after those from Pfizer-BioNTech and Moderna, to be available in the U.S. — and the only one so far to require just one dose.
The advisory panel of over a dozen vaccine and infectious disease experts gathered virtually on Friday and, after discussing the Johnson & Johnson vaccine’s safety and side effects, voted unanimously to endorse it for emergency use for people 18 and older.
An FDA analysis of Johnson & Johnson’s vaccine released Wednesday found that it was safe and effective. A study reported that the vaccine protected against COVID-19 at a rate of about 66% against symptomatic cases and 85% against severe cases. After 28 days following vaccination, there were zero cases of hospitalizations or deaths.
The Pfizer and Moderna vaccines, which are given in two doses, were found to be about 95% effective at preventing symptomatic cases. It’s worth noting that Johnson & Johnson’s vaccine study was conducted after more contagious virus variants were circulating, unlike Pfizer and Moderna’s studies.
“It’s important for people to not think that one vaccine is better than another,” expert panelist Dr. Cody Meissner, director of pediatric infectious disease at Tufts Medical Center, said Friday. “Hopefully [the CDC] will emphasize that there is no preference for one vaccine over another. All vaccines work with what appears to be equal efficacy and equal safety.”
Dr. Arnold Monto, a professor of epidemiology at University of Michigan School of Public Health, echoed the sentiment: “In this environment, whatever you can get, get.”
More than 47 million people in the U.S. have received at least one dose of a COVID-19 vaccine, according to the Centers for Disease Control and Prevention. So far, the CDC has recommended to states that people over age 65 be eligible for the vaccine, as well as front-line workers such as educators, food industry workers and public transportation employees.
The panelists engaged in hours of debate on Friday over the technical details of Johnson & Johnson’s vaccine study, including issues like protection against new virus variants.
Johnson & Johnson’s vaccine can be stored in a normal freezer or refrigerator, which makes it easier to transport and distribute. Moderna’s vaccine needs to be stored at super-cold temperatures. Pfizer recently reported that its vaccine could be stored in normal freezers and refrigerators and has submitted evidence to the FDA to update its guidelines.
