The AP agency informed about it on Tuesday. Johnson & Johnson said in a statement that she had conducted two studies with people who had been vaccinated with her Janssen single-dose vaccine in the past. Based on these studies, they found that the second dose of this vaccine caused an increase in the number of antibodies in people aged 18 to 55 years.

“A booster dose of Johnson & Johnson’s COVID-19 vaccine increased the antibody response among study participants who had received our vaccine in the past,” said Mathai Mammen, one of Johnson & Johnson’s senior researchers.
The company is currently negotiating with global regulatory agencies, including the US Federal Food and Drug Administration (FDA) and the European Medicines Agency (EMA), to use a booster dose of its Janssen vaccine.
