Should I worry about my 2-year-old playing with unvaccinated kids?

I have read articles about herd immunity and I understand the concept. But, boots on the ground, should I worry about my vaccinated son occasionally playing with a partially vaccinated 4-year-old and a completely unvaccinated 2-year-old? We're all pretty mindful of staying away when the children show signs of illness. I am interested in both medical information and how other parents have navigated this potential risk.
