The number is up from the roughly 11,000 vaccines administered on 17 May.
The government had brought 100 inoculation sites online by the end of 18 May, according to health department director-general Dr Anban Pillay. More private vaccination sites will come online in the next few days, he said.
Meanwhile, some provinces released their own vaccination figures.
On 17 and 18 May, the Eastern Cape injected more than 7,000 healthcare workers and people over the age of 60, according to health MEC Nomakhosazana Meth. She spoke on Wednesday while visiting Settler’s Hospital in Makhanda to inspect its vaccination sites.
The province had 23 sites active on 19 May and almost 200,000 registrations, she said. She gave an assurance that the province had all the fridges and cold boxes it needed to maintain the cold chain.
