The Hutterites in Alberta, from what I've heard on various talks etc, aren't anti-vaxx in the traditional sense. There is definitely some attitudes like that, but the reason the vaccination rate was so slow was a mix of distrust of healthcare professionals and also difficulty in accessing the vaccine. People would have to travel to a public health clinic which is typically quite far away. The uptake in vaccine rates among these groups in Alberta has actually gone way up since the outbreak, and since the healthcare organization has made the vaccine more readily available.
