Johnson & Johnson announced Thursday that its coronavirus vaccine is effective against the highly contagious Delta variant that brought India to its knees this past spring.
The finding will no doubt reassure the 11 million Americans who have gotten the J&J shot, as the company also noted the protection lasted eight months after inoculation.
Although there was a slight drop in potency against the Delta variant, data from two studies show the J&J vaccine was more effective against the Delta variant than the Beta variant that first surfaced in Africa. Even better, antibodies stimulated by the J&J vaccine grew in strength over time, the company added.
Both studies, which have been submitted for online publication on the preprint server bioRxiv, were small, but the company said it released the results early because of high public interest.
