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 Inoculation in this area improves peoples resistance to such attacks, examples and directions for future work are provided. Recent studies have approached inoculation by incorporating psychological reactance theory (Brehm, 1966, 1972; Brehm & Brehm, 1981) as a means to enhance resistance outcomes through inoculation theory's two key components: threat and refutational preemption. Miller, et al. (2013) focused their study on emerging adults and their reactance to persuasive appeals. Research has demonstrated that this population is in a transitional stage in life (Voyer et al., 2005) and are more likely to defend their behavioral freedoms if they feel others are attempting
