COVID-19: J&J says the booster dose of his vaccine offers a strong immune response


    Johnson & Johnson released data showing that a booster dose of its one-shot coronavirus vaccine provides a strong immune response months after receiving the first dose.

    J&J said in a statement Tuesday that it conducted two early studies on people who had previously received its vaccine and found that a second dose caused an increased antibody response in adults ages 18 to 55.

    The results of the study have not yet been reviewed by experts.

    A booster dose of the Johnson & Johnson COVID-19 vaccine further increases antibody responses in subjects who previously received our vaccine, said Dr. Mathai Mammen, Global Head of Research and Development at J&J.

    The company is in talks with regulators such as the US Food and Drug Administration, the European Medicines Agency and others about the use of booster doses of its vaccine.
