What evidence leads you to believe they don't vaccinate?
They usually don't. My grandfather (Mennonite) wasn't certain if he should put lightning rods on his barn, since he didn't want to interfere with God's will if God should decide to strike his barn.
I live among Amish farmers and they sure as heck do vaccinate their babies/toddlers. I hate it when they bottle up my doctors office because they all come at once in a van with back to back appointments spanning two plus hours. They do take very good care of their children and afford them many hours of play and attention.
"What evidence leads you to believe they don't vaccinate?"
See Part 2 of the article, which I just posted.
I don't know about Agsloss's experience but having midwifed for over 10 years for both 'Old Order' and 'Swartzendruber' Amish as well as a Mennonite community, I can definitely say that the more traditional the community the more resistant to such things.
Actually - the Amish have been extremely resistant to vaccination from the beginning of the practice.
Just a simple search of "vaccination Amish" revealed the following:
http://www.avn.org.au/Vaccination%20Information/Measles_casestudies.htm
Which actually mentions the lack of vaccinations among the Amish.
And then this from another site:
Vaccinators failed to eradicate measles, so now they claim success in reducing measles incidence between 1970 and 1987. However, it has been published that the very unvaccinated Amish communities did not report a single case of measles between 1970 and 1987. Then, since 1987, both the unvaccinated Amish and the well vaccinated outside communities started experiencing huge outbreaks of measles. Quite obviously, vaccination was totally irrelevant. Quite likely, the sustained small outbreaks of measles between 1970-87 in the vaccinated was achieved by vaccination, which kept measles occurring.
