FDA says Johnson & Johnson ($JNJ) COVID-19 booster bolsters immune system

A booster of Johnson & Johnson’s Covid-19 vaccine showed signs of significantly bolstering the immune defenses of study subjects, federal health regulators said Wednesday.

The regulators cautioned, however, that data was limited and they had to rely on J&J’s own analysis for some of the study findings, rather than conducting their own.

The Food and Drug Administration staff gave their assessment of the J&J booster data as part of the agency’s review of the company’s request for authorization of the second dose.
