Johnson & Johnson’s COVID-19 vaccine offers strong protection against the delta variant of the coronavirus, the company said Thursday. And the protection appears to last at least eight months.
The results follow similar announcements about the Pfizer and Moderna vaccines, in the fight against the fast-spreading delta strain.
In one small laboratory study, researchers observed what happened to the blood of eight vaccinated individuals when it was exposed to the delta variant. And they found that antibodies and immune system cells in the blood were highly effective at neutralizing the virus.
A second study involving 20 patients at Beth Israel Deaconess Medical Center in Boston showed similar results.
