Johnson & Johnson said Wednesday a booster shot of its Covid-19 vaccine generated a promising immune response in early stage clinical trials – though the information provided by the company in a press release was light on some details.
J&J’s vaccine requires only one dose and recipients are considered fully vaccinated two weeks after receiving the shot. The company said Wednesday that J&J recipients who received a booster dose of the shot generated virus-fighting antibodies “nine-fold higher” than those seen four weeks after a single dose.
“We have established that a single shot of our COVID-19 vaccine generates strong and robust immune responses that are durable and persistent through eight months,” Dr. Mathai Mammen, head of research and development at J&J’s Janssen vaccine arm, said in a statement.
“With these new data, we also see that a booster dose of the Johnson & Johnson COVID-19 vaccine further increases antibody responses among study participants who had previously received our vaccine,” he added.
It also raises questions about why J&J recipients need booster shots – especially after the July report showed that a single shot of its vaccine provides immunity that lasts at least eight months and appears to deliver adequate protection against the fast-spreading delta variant.
To be sure, the Centers for Disease Control and Prevention has said J&J recipients will probably need a booster dose but added it doesn’t have enough data right now to support a formal recommendation.
