>>There is no valid argument against this.<<
Children should not be vaccinated against Measles, Rubella, Mumps, Chicken Pox, TB and, not that long ago, Polio? There is no public policy argument, especially since many of these are very contagious?
Government bureaucrats can take the advice of doctors and scientists in order to help them make administrative decisions. This does not include forcing people or leading them to think they have no choice but to get vaccinated against diseases which are behaviorally spread.
