We have many who are organic farmers, but the rest douse every weed on their whole property with roundup and another weed killer that's as bad or worse (can't remember the name) they aren't careful with burning arsenic treated lumber, plastics, etc. We also have a large portion of the community which would be considered obese, men and women and even children, due to processed foods and inactivity. It's hard to consider the Amish as a whole group because the more progressive they are, the more like the typical American they are (just drive a buggy and wear different clothes), while the more strict sects are more likely to distrust the system and be more separate from the "world". I live in the third largest community and our whole area is very progressive, but I've also lived in a more strict area in IL. As a whole they do tend to distrust traditional medicine, and opt for chiropractic whenever possible. But, all in all, they are probably a little less likely to Vax.
