You're at least somewhat correct, at least judging by the headlines on realclearpolitics, for example, or by browsing politically opposed subreddits simultaneously. But I'm really astounded that you've said that anti-vaxxers are specifically right-wing. I thought it was a bit more like the flat-earth phenomenon where it's unclear who is being satirical, who supports it simply because of some disposition to conspiracy, and who actually believes that they've found evidence more compelling than the near entirety of the foundation of our scientific system - the same scientific system that has managed to create the device of incomprehensible complexity on which you're reading this comment.
