Herd immunity 

Senior Researcher at the CSIR, Ridhwaan Suliman says the current low numbers of coronavirus positive cases in South Africa is more likely linked to some level of herd immunity that has developed after the devastating third wave.

Around a quarter of adults have been fully vaccinated in South Africa. The third wave was driven by the highly infectious Delta variant.

The test positivity rate remains low at this stage and the death toll from COVID 19 continues to decline.

Dr Suliman has cautioned that a fourth wave of coronavirus is very likely towards the end of the year.
