An independent state does not pay too dear a price for its independence in accepting the sufferings of war when it cannot avoid them; a state which has lost its independence may find at least some compensation in the fact that its protector procures for it peace with its neighbours.

States should require vaccinations for communicable diseases, like measles and the mumps. But you can't catch HPV if an infected schoolmate coughs on you or shares your juice box at lunch. Whether or not girls get vaccinated against HPV is a decision for parents and physicians, not state governments.
