Children pick up many more germs than adults do, naturally. They’re children, most dont know better, and sometimes their parents don’t bother to teach them better. Children bring germs from school, the park, stores, other people, and etc. back home to their parents. Leaving your kids unvaccinated exposes them to a world of illnesses and viruses that can possibly be fatal to them. If you want your child to be healthy, please vaccinate them.
