Johnson & Johnson announced on Tuesday that it submitted data to the United States Food and Drug Administration (FDA) in an effort to get a booster shot of its one-dose COVID-19 vaccine approved for those aged 18 and older.

The company said its application was supported by phase 3 study data showing that a booster given 56 days after the original dose provided 94% protection against symptomatic COVID-19 in the US and 100% protection against severe/critical COVID-19 at least 14 days after vaccination.

According to J&J, previous studies demonstrated "that when a booster of the Johnson & Johnson COVID-19 vaccine was given six months after the single shot, antibody levels increased nine-fold one week after the booster and continued to climb to 12-fold higher four weeks after the booster."
