Conclusions
This analysis suggests that a very high intensity vaccination program that included four interventions to eliminate disparities in elderly minority influenza and PPSV vaccination rates would be cost-effective at both $50,000 and $100,000/QALY willingness-to-pay thresholds. A vaccination program including these four interventions should be considered for adoption in community-based practices seeking to address disparities in elderly minority vaccination rates. Further research on the costs and effectiveness of such programs may be warranted and could be undertaken in the form of a large pragmatic clinical trial that would likely be economically reasonable to conduct given the value of the information garnered from such a trial.
