[10] [11] In countries where tuberculosis or leprosy is common, one dose is recommended in healthy babies as soon after birth as possible. [9]
The vaccine completed a Phase I double-blind randomized controlled clinical trial that demonstrated that rBCG30 was safe and immunogenic; during nine months of follow-up, rBCG30, but not BCG, induced significantly increased Antigen 85B-specific immune responses in eight immunological assays (blood lymphocyte proliferation, antibody responses by ELISA, interferon-gamma producing CD4+ and CD8+ T ...
