Vaccinology researcher and dean of the faculty of health sciences at the University of the Witwatersrand, Prof Shabir Madhi, says that while there has been some increase in infections in the lesser-affected provinces, the severity of the previous two waves likely conferred significant community immunity, particularly when it comes to reducing risk for severe Covid-19. – Mail&Guardian (29 May 2021)
“Unless there’s a further mutation of the virus, and particularly immune-evasive mutations, it’s likely that our third wave across the country will be less severe than the first two waves, certainly when it comes to hospitalisations and death,” he concludes.
Madhi disagrees with the national health department’s methodology of measuring resurgence at one-third of the peak of the previous infection wave, saying this “doesn’t make much epidemiological sense” as it could be heavily affected by testing rates.
