BCG vaccine and one disaster, in particular, did much to harm public acceptance of the vaccine. In the summer of 1930 in Lübeck, 240 infants were vaccinated in the first 10 days of life; almost all developed tuberculosis and 72 infants died. It was subsequently discovered that the BCG administered there had been contaminated with a virulent strain that was being stored in the same incubator, which led to legal action against the manufacturers of the vaccine. Dr. R.G. Ferguson, working at the Fort Qu'Appelle Sanatorium in Saskatchewan, was among the pioneers in developing the practice of vaccination against tuberculosis. In 1928,
Inoculation theory counterarguments, the inoculation receiver will then seek out supporting information to further strengthen their threatened position. Finally, the held attitude or belief becomes resistant to a stronger attack, hence the medical analogy of a vaccine. Inoculation is a theory developed to strengthen existing attitudes and beliefs while building resistance to future counterarguments. For inoculation to be successful it is crucial that a threat (motivation for resistance) is imposed upon these existing ideas and refutational preemption (ability to build defenses against potential counterarguments) takes place after the inoculation. The argument that is presented through inoculation must be strong enough to initiate
