Survey questions
Perceived scientific agreement
To the best of your knowledge, what % of medical scientists agree that vaccines are safe? (0–100 %). 88.39 (11.41)
Autism-vaccine link
To what extent do you agree with the following statement; “there is scientific evidence for a causal link between vaccines and autism” (1 = Completely Disagree – 7 = Completely Agree). 2.43 (1.77)
Risk perception / concern
How concerned are you about the potential risk of vaccines? (1 = I am not concerned at all, 7 = I am very concerned). 3.06 (1.92)
Public support index (Strongly Disagree = 1, Strongly Agree = 7). 6.20 (1.24)
I believe that vaccines are a safe and reliable way to avoid the spread of otherwise preventable diseases (M = 6.28, SD = 1.25).  
I have already vaccinated my children or would do so if I had children (M = 6.29, SD = 1.52).
I would support policies that require people to vaccinate their children (M = 5.72, SD = 1.78).
I believe that the health benefits of vaccines outweigh the risk of any potential negative side effects (M = 6.19, SD = 1.41).
I believe that vaccines are important in maintaining and improving public health (M = 6.31, SD = 1.27).
In the interest of public health, parents should simply be required to vaccinate their children (M = 5.75, SD = 1.72).
More people ought to vaccinate themselves and their children (M = 6.20, SD = 1.48).
I believe that vaccine refusal poses a risk to public health (M = 6.02, SD = 1.62).
