Health Minister Dr. Zweli Mkhize says his department did not know when the third wave of Covid-19 could hit SA, but maintained it remained a big risk.
The Department of Health also announced that South Africans would be able to register for the vaccine from Friday through the Electronic Vaccination Data System.
Mkhize said there was no way of telling whether the next wave would be orchestrated by the 501Y.V2 or whether there will be a new variant.
