The results from the trial of nearly 480,000 healthcare workers mark the first real world test of J&J’s single-dose vaccine against the Delta variant and
support a small laboratory study the company released last month showing the single-dose vaccine offers good protection against the highly contagious strain.
The South African study, known as Sisonke, found that the J&J vaccine has an efficacy of up to 71% against hospitalization from the Delta variant, 67% against hospitalization from the Beta variant and up to 96% against death, according to a presentation of the results Friday. The data hasn’t yet been peer reviewed or published in a scientific journal.”
Not peer reviewed yet but a trial of 480,000 health care workers.
