The vaccine coverage of pneumococcal types, vaccine percentage efficacy, and stage of HIV disease in vaccine recipients are critical determinants of whether this strategy will be of value in adults.
The length of time that a population has been displaced and the HIV prevalence levels in both area of origin and area of displacement are major determinants of whether the above factors lead to an increase or decrease in HIV infection rates [ 6].
A number of studies have observed that individual assessments of the benefits and risks of disclosure are important determinants of whether individuals disclose their HIV status to anyone, including sexual partners.

Furthermore, the presence or absence of the listed cardiovascular risk factors and comorbidities are not determinants of whether to provide acute reperfusion in the event of MI and thus do not act as confounders in the comparison.
