Healthcare workers had 91% to 96.2% protection against sickness and death she said, presenting the first results in the world to show J&J’s effectiveness against the Delta variant.
06 August 2021 - 12:23Glenda Gray, left, and Linda-Gail Bekker led the Sisonke implementation study using the J&J vaccine and new results show it saves lives against the Delta variant.The J&J Covid-19 vaccine protects people against dying if they get infected with the Delta variant, Prof Glenda Gray, co-principal investigator of the Sisonke implementation study — which gave nearly half a million healthcare workers J&J jabs — said on Friday.
Gray and co-principal investigator of the Sisonke implementation, Prof Linda-Gail Bekker, launched Sisonke on Feb. 17 when the national rollout faltered and they vaccinated about 478,000 healthcare workers until May 17.Heath minister Joe Phaahla said, in the same briefing, that fewer healthcare workers had died or been sick during the third wave after being vaccinated with the J&J shot.
The Sisonke analysis found that the J&J vaccine protected against both the Delta and Beta variants, with “in fact greater effect against Delta”. Most breakthrough infections — an infection 28 days after vaccination — were mild and the reduction in hospitalisation among vaccinated healthcare workers ranged from 66% to 71%.“The side effects were completely in line with what we are seeing globally, where they have seen rare adverse events.”
