Attitudes
A) Should be allowed to send unvaccinated children to school A) 1.72 (1.13-2.6) p < 0.05
B) Worry that many of the reports of serious side effects from vaccines are accurate B) 2.03 (1.05-3,91) p < 0.05
C) Concerned the CDC/ACIP underestimates the frequency of vaccine side effects C) 2.86 (1.65-4.97) p < 0.05

CMixed providers were those who had vaccinated and unvaccinated children. A binomial framework allowed for mixed providers to contribute to the odds ratio calculation. CDC: Centres for Disease Control and Prevention. ACIP: Advisory Commitee on Immunization Practices.
