Following the publication of this article [1], it was brought to our attention that Table 2 of the Appendix contains a typographical error. The right column of the table incorrectly reads (N = 216) instead of (N = 206).

In addition, Table 3 of the Appendix contains some non-consequential rounding errors for the Mean (S.D.). The corrected table is provided below:
Table 3

Survey questions and descriptive statistics


Mean (S.D.)

Survey questions


Perceived scientific agreement


To the best of your knowledge, what % of medical scientists agree that vaccines are safe? (0% - 100%).

88.57 (10.14)

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).

2.34 (1.71)

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).

3.05 (1.88)

Public support index (strongly disagree =1, strongly agree =7).

6.09 (1.32)

I believe that vaccines are a safe and reliable way to avoid the spread of otherwise preventable diseases (M = 6.29, SD = 1.20).


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 = 5.73, SD = 1.78).


I believe that the health benefits of vaccines outweigh the risk of any potential negative side effects (M = 6.16, SD = 1.38).


I believe that vaccines are important in maintaining and improving public health (M = 6.31, SD = 1.25).


In the interest of public health, parents should simply be required to vaccinate their children (M = 5.76, SD = 1.70).


More people ought to vaccinate themselves and their children (M = 6.21, SD = 1.48).


I believe that vaccine refusal poses a risk to public health (M = 6.0, SD = 1.62).


The above errors do not influence the findings and conclusions presented in the article [1].
