According to a South African pilot study, a booster dose of Johnson & Johnson’s corona vaccine is 85% effective in preventing serious illness.
The South African Medical Research Council (SAMRC) conducted the study on health workers from November 15 to December 20. But the study is still not peer-reviewed.
The team behind the study found that a third dose largely protected the health workers in the country in areas with a lot of omicron and delta infection.
Around half a million healthcare professionals in the country have received Janssen’s vaccine as part of clinical studies.
An earlier South African study in December found that the Pfizer/BioNTech vaccine was less effective against the omicron variant overall but still prevented hospital admissions by up to 70%.
