Travelers' preferences for tick-borne encephalitis vaccination
Poulos, C., Boeri, M., Coulter, J., Huang, L., Schley, K., & Pugh, S. J. (2022). Travelers' preferences for tick-borne encephalitis vaccination. Expert Review of Vaccines, 21(10), 1495-1504. https://doi.org/10.1080/14760584.2022.2108798
BACKGROUND: This study aimed to quantify preferences and risk tolerance for a tick-borne encephalitis (TBE) vaccination.
RESEARCH DESIGN AND METHODS: A stated-preference survey instrument was administered to international travelers living in the United States to elicit preferences for a no-cost TBE vaccine when planning an international trip, conditional upon four different qualitative levels of endemic TBE risk.
RESULTS: The likelihood of choosing the vaccine increased with a destination's level of endemic risk. Most respondents (94%) would choose to receive the vaccine at the highest risk level presented in the survey (i.e. when multiple TBE cases among humans are reported year after year); 6% of the sample would choose not to receive the vaccine at any risk level. Respondents who engage in outdoor activities were twice as likely as the average respondent to choose vaccination rather than opting out of vaccination, and were one-third more likely than the average respondent to choose to receive the vaccine at the lowest risk level.
CONCLUSIONS: Respondents were highly interested in a TBE vaccine, assuming no cost, and most were willing to be vaccinated at all qualitative TBE risk levels. Respondents who participated in outdoor activities were more likely than the average respondent to choose the vaccine.
