BCG vaccine screened for active tuberculosis. BCG is also contraindicated in certain people who have IL-12 receptor pathway defects. BCG is given as a single intradermal injection at the insertion of the deltoid. If BCG is accidentally given subcutaneously, then a local abscess may form (a "BCG-oma") that can sometimes ulcerate, and may require treatment with antibiotics immediately, otherwise without treatment it could spread the infection causing severe damage to vital organs. However, it is important to note an abscess is not always associated with incorrect administration, and it is one of the more common complications that can occur with the vaccination.
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
