Immunisation medical contraindication or natural immunity

You may be able to have an immunisation medical contraindication or natural immunity recorded on the Australian Immunisation Register (AIR) if there is a valid medical reason.

To get some family assistance payments, your child must meet immunisation requirements.

What counts as a medical contraindication or natural immunity

You can only have an immunisation medical contraindication or natural immunity recorded on the AIR if you:

  • had anaphylaxis after a previous dose of a vaccine
  • had anaphylaxis after a dose of any component of a vaccine
  • are significantly immunocompromised - for live vaccines only
  • have natural immunity - for hepatitis A, hepatitis B, measles, mumps, rubella, varicella (chickenpox) and Q fever only.

Who can record a medical contraindication or natural immunity on the AIR

Only eligible health professionals can record a medical contraindication or natural immunity to a vaccine on the AIR.

These health professionals are:

  • general practitioners, as defined in the Health Insurance Act 1973
  • paediatricians
  • public health physicians
