BCG vaccine BCG vaccine Bacillus Calmette–Guérin (BCG) vaccine is a vaccine primarily used against tuberculosis (TB). In countries where tuberculosis or leprosy is common, one dose is recommended in healthy babies as close to the time of birth as possible. In areas where tuberculosis is not common, only children at high risk are typically immunized, while suspected cases of tuberculosis are individually tested for and treated. Adults who do not have tuberculosis and have not been previously immunized but are frequently exposed may be immunized as well. BCG also has some effectiveness against Buruli ulcer infection and other nontuberculous mycobacteria infections. Additionally
Inoculation theory existed for all hypotheses. The results of their experimentation yielded the understanding that inoculation coupled with reactance-enhanced messages leads to "stronger resistance effects" (p. 148). Consistent with the medical analogy of inoculation theory, Miller, et al. (2013) liken reactance-enhanced messages to a "booster shot," increasing the success of the inoculation. Another unique feature of the study is examining low-controlling language versus high-controlling language and its impact on affect and source credibility. Similarly, Miller, et al. (2007) utilizes psychological reactance theory (Brehm, 1966, 1972; Brehm & Brehm, 1981) to avoid or eliminate source derogation and message rejection. In this study, their
