Natural Immunity is a type of immunisation medical exemption on the AIR. A laboratory test or physician based clinical diagnosis confirms natural immunity to a disease.
A natural immunity has no end date and can only be recorded on the AIR for hepatitis B, measles, mumps, rubella and varicella.
Recording a natural immunity to a disease means that the individual is not required to receive that disease component of a vaccine in order to be considered up to date with immunisations for the purposes of: child care enrolments overdue reminder letters overdue reporting for providers, and meeting requirements for family assistance payments
However, the Department of Health considers the individual is still due/overdue for any remaining elements in the vaccine. For example, if an individual has a recorded natural immunity to mumps, they are still due/overdue for measles and rubella. This shows in their immunisation status on the AIR.
Following the positive identification of an individual and using their individual identifier, this service will:
Record a vaccine exemption due to natural immunity, and Add the vaccine exemption to their natural immunity history with the notification date as the date recorded on the AIR
