Now, Stefan Kaufmann, director of the Max Planck Institute for Infection Biology in Berlin, Germany, and colleagues have devised a way of boosting BCG’s power. Their souped-up vaccine was 10 times more effective than conventional BCG in protecting mice from infection. And it slashed the presence of “drug-resistant” TB bacteria to about 1% of its initial level in mice infected with this strain - the standard BCG had no effect.
