Brief Summary
- 1.To determine if BCG immunisation at birth, compared to no BCG immunisation, leads to a reduction in measures of allergy and infection in the first 12 months of life.
- 2.To evaluate the immunological mechanisms underlying the non-specific effects of BCG by comparing markers of immunity between the BCG and non-BCG groups.

- English speaking mother;
- An informed consent form must be signed and dated by their parent(s) or legally acceptable representative after the nature of the study has been explained and prior to any study assessments/procedures;
- The infant's mother has screened negative for HIV during this pregnancy;
- Born no earlier than eight weeks before estimated date of delivery;
- Birth weight \>1500g.
- The legal guardian expects to be able to complete four online/phone questionnaires over the infant's first 12 months of life and for the infant to be available for skin prick testing at RCH between 12-16 months of age.
You may not qualify if:
- Any indication for BCG immunisation in the first 12 months of life including:
- likely travel to a high tuberculosis (TB) incidence country in the first year of life.
- Aboriginal and Torres Strait Islander babies living in parts of Australia where the incidence of TB is higher
- newborn babies, if either parent has leprosy or a family history of leprosy
- newborn in contact with a patient with TB.
- Known or suspected HIV infection
- Treatment with corticosteroids or other immunosuppressive therapy, including monoclonal antibodies against tumour necrosis factor-alpha (TNF-alpha) (e.g. infliximab, etanercept, adalimumab).
- Born to a mother treated with bDMARDS (e.g. TNF-alpha blocking monoclonal antibodies) in the 3rd trimester;
