In a prospective cohort study of 1670 healthcare personnel (HCP) providing direct patient care at Scott & White Healthcare in Texas and Kaiser Permanente Northwest in Oregon and Washington, we examined the potential impact of twelve vaccine promotion strategies on the likelihood of being vaccinated. Internet-based surveys were conducted at enrollment (Fall, 2010) and at post-season (Spring, 2011), which asked HCP whether twelve vaccination promotion strategies would make them “much less” to “much more” likely to be vaccinated next season (on a 5-point Likert scale). Overall, 366 of 1670 HCP (22%) were unvaccinated. Half (50%) of unvaccinated HCP self-reported that a vaccination requirement would make them more likely to be vaccinated and most (62%) identified at least one strategy other than a vaccination requirement that would make them more likely to be vaccinated. In sub-groups of unvaccinated HCPs with specific barriers to vaccination, about one in three (range = 27–35%) indicated that interventions targeting specific vaccination barrier would increase the likelihood they would be vaccinated. However, in all cases, significantly more unvaccinated HCP reported that a vaccination requirement would increase the likelihood of vaccination than reported a targeted intervention would have this effect (range in difference scores = +11–23%).
