Jehovah's Witnesses are not a faith healing community and their religion is not anti-vaccination [1] [2]. Christian Scientists do first turn to prayer for healing, but it is not part of the dogma. Their church is fine with members who get vaccinated [3].
Good to know! I was wary about naming names and am now bummed I labeled them wrongly, but had wanted to illustrate a familiar example of skepticism towards a system as distinct from debate within a system.
