Is it necessary to isolate my dog for 3 days after a nasal C5 vaccine?

Pet's info: Dog | Dachshund | Male | 1 year and 2 months old

Yesterday my dog had a C5 vaccination up his nose, the vet recommended he stays away from other dogs for 3 days. Is this necessary? And what are the consequences if he doesn’t. He has had all his c3 vaccinations, we just had to get the c5 so he can stay in a kennel

I agree with your vet. The reason is that a modified live virus is used in that vaccine so potentially your dog could infect other unvaccinated dogs in that time period. So, the consequence is that he could infect other dogs.
