ABC NEWS – A real-world study of South African health care workers found that two doses of the Johnson & Johnson COVID-19 vaccine offer 85% protection against hospitalization from the omicron variant. Separately, the company announced new data from a laboratory study that shows its vaccine likely also works well as a booster for people who got the Pfizer shots originally. The lab study specifically tested two types of immune system responses — antibody and T-cell responses — against the omicron variant. Using the J&J vaccine as a booster raised people’s antibodies and T-cells to levels higher than those seen among people who got a third dose of Pfizer.
