An advisory body to the U.S. health authority has recommended a booster shot, or booster shot, of the Johnson & Johnson pharmaceutical subsidiary Janssen's COVID-19 vaccine.

It is the third after Pfizer-BioNtech and Moderna.

The advisory body recommended that the Janssen booster shot be administered at least two months after receiving the Janssen vaccine, which ends with a single dose.

Unlike Pfizer and Moderna's Booster Shot, the target of vaccination has been greatly expanded to all adults over the age of 18.
