Questions have been raised about the stability of the health department's electronic vaccination data system (EVDS) after reports that it "collapsed" last week.
According to two sources with direct knowledge of the department's vaccination strategy, serious problems were encountered last week after more than 1 million people had registered on the EVDS.
By Sunday evening, it was unclear whether any South Africans, who registered to be vaccinated from today under the second phase of the vaccine rollout programme, received SMSes confirming their appointments.
