[ANALYSIS] SA likely to miss herd immunity target: scientist eNCA

A more transmissible coronavirus variant first identified in South Africa late last year fuelled the country's second infection wave and delayed the start of vaccinations in February.

Vaccinology professor Shabir Madhi, lead investigator on the Oxford/AstraZeneca vaccine trial in South Africa, said the local variant and a third wave of infections expected later this year were likely to hinder inoculation plans."We need to recalibrate... our understanding of what we can actually achieve with COVID-19 vaccines," Madhi told a virtual panel discussion.

Inoculations started last month with jabs developed by US pharma giant Johnson & Johnson.The rollout was briefly delayed after a study found that AstraZeneca vaccines - the first doses to land in the country - only offered limited protection against mild and moderate disease caused by the new variant.

Substantial quantities of the vaccines are only expected in April and May.Infections are meanwhile expected to resurge in June or earlier if a cap on mass gatherings is lifted during the upcoming Easter holiday.So far South Africa has secured 11 million Johnson & Johnson vaccines and 20 million doses of a jab developed by Pfizer.

Another 12 million doses are expected from the WHO-backed vaccine pooling initiative Covax and an undetermined amount from the African Union.The country is the worst-hit by the pandemic in Africa, with over 1.5 million cases and almost 50,000 deaths recorded to date.
