BCG vaccine 400 per 100,000 in that higher risk context). The age of the person and the frequency with which BCG is given has always varied from country to country. BCG is prepared from a strain of the attenuated (virulence-reduced) live bovine tuberculosis bacillus, "Mycobacterium bovis", that has lost its ability to cause disease in humans. Because the living bacilli evolve to make the best use of available nutrients, they become less well-adapted to human blood and can no longer induce disease when introduced into a human host. Still, they are similar enough to their wild ancestors to provide some degree of
Inoculation theory restore original beliefs and attitudes after the counterarguments have been made. Results of the research reinforced prior conclusions that refutational same and different treatments both increase resistance to attacks. More important, results also indicated inoculation was superior to post hoc refutation when attempting to protect original beliefs and attitudes (Pfau et al., 1990). Much of the research conducted in health is attempting to create campaigns that will encourage people to stop unhealthy behaviors (e.g. getting people to stop smoking or prevention of teen alcoholism). Compton, Jackson and Dimmock (2016) reviewed studies where inoculation theory was applied to health-related messaging. There
