BCG vaccine nesting birds and rusted electrical conduits. The resulting closure of the plant for over two years resulting in shortages of bladder cancer and tuberculosis vaccines. On October 29, 2014 Health Canada gave the permission for Sanofi to resume production of BCG. The global supply situation was analyzed in 2017 and concluded that the global supply is sufficient to meet forecasted BCG vaccine demand but risks for shortages remain mainly due to supply concentration. A weakened strain of bovine tuberculosis bacillus, "Mycobacterium bovis" is specially subcultured in a culture medium, usually Middlebrook 7H9. Some BCG vaccines are freeze dried and become
Inoculation theory of this study is to determine how to improve the effectiveness of the inoculation process by evaluating and generating reactance to a threatened freedom by manipulating explicit and implicit language and its intensity. While most inoculation studies focus on avoiding reactance, or at the very least, minimizing the impact of reactance on behaviors, in contrast, Miller, et al. (2013) chose to manipulate reactance by designing messages to enhance resistance and counterarguing output. They posit seven hypotheses in this study. H1 aims to discover if reactance-enhanced messages warning of a potential attitudinal threat negative affect and cognitions toward the attack message
