Johnson & Johnson released data showing that a booster dose to its one-shot coronavirus vaccine provides a strong immune response months after people receive a first dose.
J&J said in statement Tuesday that it ran two early studies in people previously given its vaccine and found that a second dose produced an increased antibody response in adults from age 18 to 55. The study’s results haven’t yet been peer-reviewed.

Israel is set to begin preparations to administer fourth doses of the
coronavirus vaccines as the country deals with soaring cases despite its trail-blazing roll-out of jabs.
The country’s national coronavirus czar Salman Zarka said the country needs to prepare for a fourth injection, which could be modified to better protect against new variants of the virus.
‘It seems that if we learn the lessons from the fourth wave, we must consider the [possibility of subsequent] waves with the new variants, such as the new one from South America,’ he said at the time.
‘Thinking about this and the waning of the vaccines and the antibodies, it seems every few months — it could be once a year or five or six months — we’ll need another shot.’
He added that he expects Israel to be given out vaccines that had been specially adapted to cope with different variants of the virus by late 2021 or early 2022.
While Israel is seeing record case numbers in its fourth wave, the jabs are still protecting against severe illness with Covid deaths running at about half of the level of its second wave.
