Adolescents trust physicians for vaccine information more than their parents or religious leaders.

Although, evidence clearly supports vaccination as the most cost effective approach to controlling infectious diseases there are many individuals questioning, delaying and refusing vaccines. The main purpose of this study was to find out what source of information adolescents trust the most on vaccines. We conducted a cross-sectional survey of public high school students using a paper-based questionnaire in a region with a high rate of vaccine acceptance to assess sources they trusted most for vaccine information. Surveys were administered over a one-week period in the fall of 2017. We gave forms to 200 students to obtain parental consent and student assent and then distributed our questionnaire to the 125 students who completed these consent/assent forms. A total of 105 completed questionnaires were returned. The major finding was that students reported physicians as their most trusted source for vaccine information. Secondary analysis was performed looking at the perceptions teenagers have relative to risks and effectiveness of vaccines for the prevention of communicable diseases. Most teenagers (62%) reported their physician or other medical professional as the most trusted source and 24% cited parents/guardians. We found that physicians were the most trusted source for information about vaccinations, above parents, in this group of high school students.
