I would offer him some pedialyte or water/juice for a while instead of formula. If he is vomiting and has
Diarrhea his little system may not need the formula, but may really need the fluids.
I would just make sure he isn't dehydrated, and give his body the fluids it needs to flush the virus out. And call first thing in the morning. If he becomes lethargic at all I would take him to a hospital ASAP, and I would go ahead and call the 24 hour number of my pedi, or call the hospital for advise.
