The Johnson & Johnson Covid-19 vaccine protected between 91 and 96% of healthcare workers against death.
This, according to researchers heading the Sisonke Covid-19 vaccine study, which was piloted here in South Africa.
According to co-lead investigator, professor Glenda Gray, the study was rolled-out to just under 500-thousand healthcare workers at 120 health-care sites.
Gray says the vaccine also proved to be effective against the Delta-variant of Covid-19.
