This thread is fast moving and has many pages but back in October I posted in here a similar story. My uncle basically went through the same thing as your brother. He became involved in this really cult-ish church ((where ironically many of the parishioners home school their children) also if you want to read about some really bat shirt crazy religious weirdos, it's called the Philadelphia Church of God)) and he & his wife refused to get vaccinated. They had been sick for 2 weeks when my uncle said he was having trouble breathing.
