Just another vaccination question...?

So my son has been vaccinated according to his doctors schedule... i let the doctor take control... like many other moms on here say, "the benefits strongly outweigh the risks." But is it possible for a child to receive absolutely no vaccinations? How would school work, a child cant go to school without being vaccinated right or am I just misinformed? Also for some mothers, did you skip certain vaccinations? What do you plan to do for school?
