I do as it is included in with the other vaccines (DHLPP). I do give limited vaccines once they are older, limioted as in not that often, they still get the same shots.
Once my dogs go through their puppy series (or 1-2 sets if they are older when I rescued them) they get the next one one year later when they are due. After that they only get vaccinated once every 2-4 years depending.
