This is something lots of people don't even have on their radar.  What a damned shame - people can be fairly spacey, it would seem.  The things have been around for certain since I was a kid because my Dad raised grass-fed Hereford Beef cattle and refused to vaccinate them.  Back then you could pick and choose what you did or didn't want to do.  In today's American society, everything is "decided" for you whether you like it or not.  Another shame.
