South Africa Sisonke study says Johnson & Johnson booster reduced covid hospitalizations by 85%
The study, which has not yet been peer reviewed, looked at hospital admissions from mid-November to mid-December, as the country experienced a wave of omicron infections, and compared the boosted health-care workers with people who had not been vaccinated. It found that the booster was about 85 percent effective in preventing hospital admissions from covid-19, one to two months after the second dose.
