The data comes from 344 volunteers who got an additional dose of the vaccine as part of a clinical study.

Moderna made the announcement in a press release, but the research has not yet been peer-reviewed. Pfizer-BioNTech has also asked for authorization for a booster dose of its vaccine. The FDA has scheduled a meeting for September 17th to discuss the need for boosters for the general population.

The FDA and the Centers for Disease Control and Prevention have already recommended a third dose of both the Pfizer and Moderna vaccines for some immunocompromised people. Meanwhile, health officials are already preparing to roll out COVID-19 boosters, according to a plan announced by the White House on August 18th.

The plan calls for all adults who received a two-dose vaccine to be eligible for an additional jab 8 months from when they got their second shot.
