Dis-Chem has confirmed that four staff members have been arrested for allegedly issuing fraudulent vaccination cards at a vaccination site.
The retail pharmacy chain says these were temporary employees who were nabbed at its branch at Krugersdorp President Square on the West Rand.
It's stressed that this was an isolated incident.
Dis-Chem's explained, in a statement, that discrepancies were picked up during daily vaccine stock management practices and routine checks with the government's EVDS system.
CEO Iven Saltzman says they acted immediately and that it was upsetting to see that a small number of individuals felt they could take advantage of the vaccine roll-out programme.
