Notice I didn't say you should be forced by law! There is even a controversy about the shingles vaccine, which has a limited effectiveness compare with some vaccines. Some doctors don't even recommend it. Occasionally, it will bring on a case of shingles. But, over all, I think it's a better idea to get the vaccine than not. This is a decision that can be negotiated in a rational manner.
But, the primitive emotions that these decisions stir in those who have no real historical memory of disease in the 20th century!
