The Amish do go to hospitals and many do, when educated get vaccines for their children though as to what they are doing with the covid vaccinations I don’t know. The level of such involvements with the medical system depends of the belief traditions of each order of Amish, old order Mennonite, and so forth down through the sects as well as the amount of information that has been made available to the various sects.
I’m glad God has blessed you with 9 healthy children but then perhaps some of “the righteous have no need of a physician, but the sick”/per Jesus Christ. Yet even the blind from birth may have been so afflicted through no fault of anyone’s own but rather for the glory of God to be made known...like the BLIND autistic boy I saw on a video singing...”Open the Eyes of my Heart Lord...I want to see you!”
Most of our Midwest Amish do not get vaccinations. In my last conversations with some of them, they clearly see this leading to the “Mark”. I am proud of them!
