BCG vaccine of 2004 the vaccine is given to about 100 million children per year globally. The main use of BCG is for vaccination against tuberculosis. BCG vaccine can be administered after birth intradermally. BCG vaccination can cause a false positive Mantoux test, although a very high-grade reading is usually due to active disease. The most controversial aspect of BCG is the variable efficacy found in different clinical trials, which appears to depend on geography. Trials conducted in the UK have consistently shown a protective effect of 60 to 80%, but those conducted elsewhere have shown no protective effect, and efficacy appears
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
