PHILADELPHIA (KYW Newsradio) -- People who got the Johnson & Johnson COVID-19 vaccine may soon need to roll up their sleeves again. The company says new data shows that booster doses of its one-shot coronavirus vaccine generate a big spike in antibodies.
Results show the initial shot of the J&J vaccine holds up pretty well for eight months. But after a second dose was given, it offered even more protection against COVID-19.
In clinical trials, participants who got a J&J booster shot six to eight months after their initial J&J shot saw antibodies increase nine times higher than levels about a month after the first shot.
The data still needs to be peer reviewed.

The company says it is in talks with regulators at the FDA and CDC about offering boosters at least eight months after its first dose is given.
The administration of President Joe Biden last week said they hope to see booster shots rolling out the week of Sept. 20, but they mentioned only Pfizer and Moderna. J&J is two months behind those two vaccine providers.
The CDC said people who got the J&J shot should wait for the booster to get the green light, and not get a dose of a different vaccine.
