When could we see Johnson & Johnson's single-dose vaccine?

[KARE 11 News, January 05, 2021] Johnson & Johnson's investigational COVID-19 vaccine has been called a potential "game-changer." If all goes well, J&J hopes to seek emergency use authorization for its single-dose vaccine in February. Allina Health is running the only clinical trial site in Minnesota part of the study called "ENSEMBLE."

The Phase 3 trial initially had a goal of enrolling 60,000 participants worldwide.

"They were obviously getting a lot more COVID cases than they were projecting initially so they didn't think they needed to enroll 60,000; they only needed to enroll 40,000," explained Dr. Frank Rhame, an Allina Health infectious disease physician and site principal investigator of the trial.
