NCT01906853

Brief Summary

  1. 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. 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.

Healthy VolunteersYes
Age GroupsChild (0-17)

You may qualify if:

  • Less than 10 days old;

  • 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;
