Hi Andrea,
That kind of exposure is a more natural route exposure, so it's far less likely to be harmful than getting injected. In case you missed it, I explain this vast difference here. One part of it is unnatural: the exposure to multiple different viruses at once.
So, it's possible he could get sick. If he does, I'd suggest seeking out a homeopathic vet for help through it. See my Resources page for the AVH list. You can hire someone for telephone consulting if no one is close.
If there's still time, you could also help avoid immune disease by strengthening your pup's immune system before the shots are given to the others. If the breeder will feed a natural supplement that beats all in doing this work, you can send a can of Transfer Factor Canine Complete for her to scoop on this guy's food twice a day.
I applaud your stand against routine vaccines, but now you need to decide what you'll do in place of them. You know about the natural exposure protocol from Dr. Manziano, yes?
