JOHANNESBURG - The Health Department says low stock levels have hindered the vaccine rollout.
But it says with the arrival of more doses, it hopes to ramp up the drive next week.
Among the vaccines to arrive is a donation from the US.
"We were running very low on stocks and unable to gear up all of our capacity both in the public and private sector," said Nicholas Crisp from the National Health Department.
"Now those sites that we have been unable to open up -- that were asking for us to provide them -- can start to happen during the course of this week. We got J&J vaccines on Thursday last week.
"We received 2.8 million over the weekend, there was another almost 1.5 million [that] arrived on Sunday afternoon and during the next couple of days, the remainder of the 5.6 million arrives," Crisp said.
"By the end of this week we should be gearing up and certainly by next week we should be in full float again."
