Durbach N. "They might as well brand us: Working class resistance to compulsory vaccination in Victorian England." The Society for the Social History of Medicine. 2000; 13:45-62.
Now I'm in the final throes of my PhD and so don't have the time to follow-up on this reference. If anyone else does, I'd be fascinated to hear the evidence that Durbach offers. I should point out that I'm not particularly skeptical that this happened, since one can find "local clergy" who advocate just about any position. It seems odd, however, since 1) the New Testament specifically states that no animal is "unclean"; and 2) the smallpox vaccine came from cowpox, which in turn came from ... wait for it ... cows. Cows are considered "clean" animals in the Old Testament. So it's difficult to see how the smallpox vaccine could be considered "unchristian" or even "unjewish".
