Medical aids have to follow the rules of the national vaccine rollout as set out by the Department of Health. Medical aids are only allowed to vaccinate a certain age group as announced by the Department of Health. The EVDS will ask the client if they have a medical aid. If they do, they will need to enter the name of the scheme and also their medical aid number. The system will try to send medical aid members to private sites (if there is one in their area) but they may be invited to a public site.
