You made that decision for your children who were too young to decide for themselves. I made that decision for mine, too. I'm amazed that your schools can insist on a child's vaccination. Quite rightly ,the advocacy by schools here is strong, but enforcement is considered to be a step too far. As for travel, there are countries I can't go to unless I'm vaccinated against this, that or the other. Two things: first, you don't have to travel. If you don't, you don't have to get the vaccine. You still have that choice. Telling someone they'll lose their livelihood is somewhat less of a choice, to say the least. Second, it could be the country you're going to that does the insisting.
