...overcrowding, malnutrition and ignorance, its prevention is largely a sociological problem. Doctors, however, have long searched in vain for a medical weapon that would work against TB with the sure efficacy of, say, the smallpox vaccine against smallpox. The best they have found so far is the vaccine called BCG, which was first tried out on calves in 1908 at France's Pasteur Institute...
...BCG is far from being the perfect weapon. Some doctors think that it can be downright dangerous; even its most ardent partisans admit that it will not do a complete immunization job in every case. It can be used only on patients showing no active sign of the disease. An added difficulty is the fact that no one can be certain just how effective BCG is until it is made the only preventive agent in a long-term experiment on a large mass of people...

But socially conscious Denmark has gone further than most nations in eliminating the factors that encourage tuberculosis. In lands where all else is hopeless, BCG has been given a fairer chance to make a statistical case for itself. Throughout the crowded, war-torn areas of Europe and the East, where general health conditions are at their worst, the International Tuberculosis Campaign, jointly sponsored by several U.N. and Red Cross organizations...
...Britain, vaccination with BCG has been adopted by the Ministry of Health as an official preventive measure against TB. A major fear among many U.S. doctors, who have thus far not been able to make up their minds about it, is that universal acceptance of the vaccine might lead the public to neglect other preventive measures, most importantly the constant effort to track down the disease by widespread X-ray chest examination...
...vaccine's reputation suffered a serious setback in Lübeck, Germany, in 1930, when 72 of 251 infants died after being vaccinated with what was thought to be BCG. Investigation proved that the children had been vaccinated with another culture, but the outcry was so great throughout the world that BCG was regarded with suspicion for years...
