SAN FRANCISCO (KGO) -- Johnson and Johnson has fully enrolled participants for its late-stage trial of a COVID-19 vaccine, according to a company statement Thursday.

One big advantage with this potential vaccine is it only requires a single-shot.

Unlike the Pfizer and Moderna vaccines, Johnson and Johnson's version has been touted to only require a single-dose, although a study involving a two-dose regimen is also being conducted.

Interim data should be available by the end of January. The company plans to submit an emergency use authorization request to the FDA in February, according to Johnson & Johnson's statement.

The ENSEMBLE trial was paused in October for a week, when a trial participant fell ill.
