Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Use of three different BCG vaccine strains (BCG-Denmark, BCG-Japan, BCG-Russia) for immunisation at birth. Immunisation at 2 months of age with one BCG vaccine strain (BCG-Denmark). In all study groups 0.05ml of BCG will be administered intradermally.
Intervention code [1] 2711 0
Prevention
Comparator / control treatment
BCG vaccine strains will be compared with one another. Dose under 1 year of age 0.05 ml. Infants immunised at birth will be compared with those immunised at 2 months of age.
Control group
Active

Outcomes

Summary
Brief summary
This study is investigating the influence of vaccine strain and age at immunisation on the immune response in children to Bacille Calmette-Guérin (BCG) immunisation. The underlying hypothesis is that there is a measurable difference in the qualtitative and qualitative immune response which may be associated with differences in the level of protection
