Trial of Two Strains of BCG

Summary

The investigators aim to conduct a randomised controlled trial comparing two Bacille Calmette-Guérin (BCG) strains currently used in Guinea-Bissau, the Danish and the Russian, in terms of prevention of neonatal and early life morbidity and mortality, immune responses and adverse events related to BCG vaccination. The primary outcome will be hospital admissions within 6 weeks of age.
