Does BCG work?
BCG can prevent someone getting TB about half the time although estimates vary widely. The protection BCG provides becomes less with time since vaccination. This means that many people develop active TB even though they received BCG. Although BCG has been used widely for a long time the rates of TB in countries that use BCG have not changed. One third of the world’s population has TB infection and two million people a year die of TB. BCG alone is not enough to stop the spread of TB.
