Data Shows J&J Booster Results In 9x Antibody Response

A new study finds that giving a booster dose of the Johnson & Johnson shot six months after primary vaccination results in a 9x increase in antibody response.

From J&J:

Johnson & Johnson today announced data supporting the use of its COVID-19 vaccine as a booster shot for people previously vaccinated with the single-shot Johnson & Johnson vaccine.

In July, the Company reported interim Phase 1/2a data published in the New England Journal of Medicine that demonstrated neutralizing antibody responses generated by the Johnson & Johnson single-shot COVID-19 vaccine were strong and stable through eight months after immunization.

In anticipation of the potential need for boosters, the Company conducted two Phase 1/2a studies in individuals previously vaccinated with its single-shot vaccine.

New interim data from these studies demonstrate that a booster dose of the Johnson & Johnson COVID-19 vaccine generated a rapid and robust increase in spike-binding antibodies, nine-fold higher than 28 days after the primary single-dose vaccination.
