Per Yale's study: "There was a modest minority of respondents who held a negative orientation toward vaccines. These respondents, however, could not be characterized as belonging to any recognizable subgroup identified by demographic characteristics, religiosity, science comprehension, or political or cultural outlooks.

Indeed, groups bitterly divided over other science issues, including climate change and human evolution, all saw vaccine risks as low and vaccine benefits as high. Even within those groups, in other words, individuals hostile to childhood vaccinations are outliers."

This just one of the studies that shows your assertion to be incorrect.
