That is really cool. We have a couple of nasal vaccines available in Vet Medicine and they are very effective. Kind of difficult to administer to an uncooperative dog, but that's another story :)
It looks like this vaccine may be a year or more away as it has to go through phase 2 and 3 trials successfully before approval.
The great things about medical science right now is that the techniques have advanced so much in the recent years and there are so many people/businesses and countries working on this that we're probably going to get something that works in amazingly short time in terms of normal vaccine development time frame.
