To clarify- as long as un-vaccinated kids are surrounded by other kids who DO have vaccinations, they are protected by "herd immunity". There is no way for the infection to spread if most kids are vaccinated. However if an un-vaccinated kid goes to a place where many other people aren't vaccinated, watch out. Also if the level of other unvaccinated kids reaches a high level, it will also be a problem. Unvaccinated kids benefit from everyone else getting vaccinations. If your kid is unvaccinated, I would be careful about going to airports and other places where there are crowds of people from other places.
