I would refer this question back to your doctor whose nurse administered the vaccine. In the nasal mist technology all of it doesn't go in one nostril but divided in both with a "click" mechanism in the syringe. I would not, however, worry. If your child is under ten, there will be another dose. If over ten years old and receiving only one dose, much will depend on the volume distributed to the nasal mucus membranes.
