>>>That is a good question. My first reaction is to say yes, why not? Seems like if there was an opportunity to save someone from getting cancer it shouldn't be hindered by someones religions point of view.

>What about cigarettes in that case. Making them illegal would avoid lots of cancers and respiratory and cardiovascular disease. I don't think there would be religious objections to that and removing access to poisons is far less invasive than forcing injections on somebody against their will.

A few flaws with the logic here. If there was a vaccine for the cancer caused by cigarettes then sure I'd be for that.
Do you know anything about the Christian Science religion? They say that a person should have no medicine or medical care of any kind. Every few years there is something in the news about how some followers of this religion has let their child die simply because they wouldn't get them some very simple medical care. I think it's less invasive to give a kid a shot than to let them die.
