LONDON (AP) — Johnson & Johnson released data showing that a booster dose to its one-shot coronavirus vaccine provides a strong immune response months after people receive a first dose.
J&J said in statement Tuesday that it ran two early studies in people previously given its vaccine and found that a second dose produced an increased antibody response in adults from age 18 to 55. The study’s results haven’t yet been peer-reviewed.
“A booster dose of the Johnson & Johnson COVID-19 vaccine further increases antibody responses among study participants who had previously received our vaccine,” said Dr. Mathai Mammen, global head of research and development at J&J. The company previously published data showing its one-shot dose provided protection for up to eight months after immunization.
