- Johnson & Johnson said data shows that people who receive a second shot of its COVID-19 vaccine see antibody levels increase nine-fold
- The firm says this is evidence that J&J recipients should be given booster shots eight months after receiving the first dose
People who received a second shot of the vaccine six to eight months after their first shot saw antibody levels nine-fold higher than those who received a single dose.
The New Jersey-based company says the data provide evidence that J&J recipients should receive booster shots eight months after their initial vaccination.
It comes after the White House announced it plans to roll-out booster shots for people who receive the two-dose Pfizer-BioNTech and Moderna vaccine.

J&J says it plans to submit data to the U.S. Food and Drug Administration (FDA), which is currently reviewing similar data from Pfizer and Moderna.
The company hopes that it can join its rival vaccine makes when boosters shot start being distributed on September 20.
‘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,’ said Dr Mathai Mammen global head of research and development at J&J 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.
‘We look forward to discussing with public health officials a potential strategy for our Johnson & Johnson COVID-19 vaccine, boosting eight months or longer after the primary single-dose vaccination.’
