I teach martial arts, and my wife teaches dance. I know of one student for sure (And I would presume that there are at least a few others) that have not received the normal United States progression of childhood inoculations.

I also have a <6 month old newborn that occasionally gets taken to the classes with us as we have somewhat conflicting schedules.

How much (if any) do I need to limit the exposure of the newborn to children that are not vaccinated?

There seems to be a link (as one would expect) between areas with a higher concentration of unvaccinated individuals and disease outbreaks (see this article and the source data map).

The recent (2015) measles outbreaks in California are a good example: at least 70-80% of those infected were unvaccinated (including a number of newborns too young to be vaccinated).

State officials say that 28 were not vaccinated at all, one was partially vaccinated and five were fully vaccinated. Six of the unvaccinated were babies, too young to be vaccinated. (source)

Simply put, unvaccinated individuals are more likely to be carrying a vaccine-preventable disease compared to the rest of the population. If your newborn is not vaccinated yet he or she is at risk. In the case of measles or whooping cough, an infection could turn deadly, as can many others.

I'm not an expert in pathology, nor am I a parent, but I would at the very least not let these individuals hold or come near your newborn, and would preferably keep my newborn completely away from them until a later time.

    Everyone is at risk when in proximity to unvaccinated people. Especially if there are enough of them to be above the line for herd immunity.

    +1 for the advice to keep the infant away from unvaccinated people. Given that polio is extremely contagious and airborne, I wouldn't allow my infant to even be in the same room.
