Africa has largely avoided the devastating impact of the preceding COVID-19 waves due to a variety of reasons per our blog archive.  The situation is more precarious now given limited vaccine rollout and the Delta variant. However, Johnson & Johnson, which offers the single-shot vaccine, released some very encouraging news today based on a trial in South Africa. Scroll down for more.

Per Bloomberg:

“Johnson & Johnson’s Covid-19 vaccine helps prevent severe disease among those infected with the delta variant, according to a trial involving almost 480,000 health workers in South Africa. The study, known as Sisonke, provides the first large-scale evidence that the J&J vaccine works against this dominant variant, according to trial co-lead Glenda Gray.

It’s probably more protective against delta than it was with the earlier beta strain, she said in a presentation Friday.

The single-dose shot was 71% effective against hospitalization and as much as 96% effective against death, she said. It also demonstrated durability of eight months.”

“These results show there is no need for a booster yet,” said Gray, who is president of the South African Medical Research Council.

“While the J&J vaccine is a key element to South Africa’s vaccination plan, the country temporarily paused its use in April after the U.S. decided to suspend the shot because of its link to rare blood clots. Other data have raised questions about how well the shot holds up against the highly contagious strain that has driven renewed outbreaks in countries including the U.S. and China.”
