The Amish got it right. Pretty much everyone else didn't.
They took a very smart, logical approach. America & so many other countries behaved like ignorant fools. I see foolish people still walking even outside, driving alone in their cars, with paper masks. Fearful and foolish.
The Amish never had to worry because Covid never existed in the first place. It was just repackaged flu or any variation of mild or serious respiratory illness.

“So, how did the Amish achieve herd immunity at such an accelerated pace?”
They didn’t. Herd immunity is a garbage concept based on the bigger garbage concept of the germ theory.
Where did this "wire report" come from? I can't find a single news article on the Amish and COVID on google news going back a full month, which of course helps to demonstrate the main point of your post.
So what was the covid death % / age versus regular seasonal flu for the Amish community?
Having recovered from Corona as it was called in early 2020 (vicinity of Wuhan residents) I was able to be in close unprotected contact with systematically sick (covid) people for years without issues.
In 2022 after moving to México the unvaccinated experienced a lot of hostility from non-Mexicans for NOT getting sick. In 2022 every 2-3× jabbed person I know got sick from covid and many were angry at those who didn't. The explanation that you didn't/couldn't get covid from people without covid would make angry sick covid vaccinated even more angry. Thankfully this was the minority of the jabbed, possibly because travel to México was prohibited or not recommended at the time.
