Johnson & Johnson joins the others: yes to the injection of the “Booster” vaccine
Sensing the deal, Johnson & Johnson, which until now was the only single-dose vaccine, joined the other companies and recommended an additional “Booster” injection of the vaccine. This is while its vaccine is being launched particularly in low-income African countries that hoped to vaccinate citizens only once.
The company made the announcement Wednesday , following the results of provisional data from two phase 1 / 2a studies in individuals previously vaccinated with its vaccine.
"New interim data from these studies show that a booster dose of the Johnson & Johnson COVID-19 vaccine generated a rapid and robust rise in spike-binding antibodies, nine times greater than 28 days after the single-dose primary vaccination," according to a statement from the company.
"Significant increases in binding antibody responses were observed in participants aged 18 to 55 and in those 65 and older who received a lower booster dose," he added, stating that he presented the study summaries to medRxiv on August 24.
This follows the July publication of interim study data in the New England Journal of Medicine which showed that neutralizing antibody responses generated by Johnson & Johnson's single injection COVID-19 vaccine were strong and stable eight months after immunization.
“We have established that a single injection of our COVID-19 vaccine generates strong and robust immune responses that are durable and persistent for eight months. 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, ”said Mathai Mammen, Global Head of Janssen Research & Development, Johnson & Johnson.
So even those who have made the single-dose vaccine, even for simplicity, risk having to come back for a recall after the first eight months. In short, life for the vaccinated is always a bit complex.
