This is a question for your vet, and/or your mentor (provided he/she lives in the same area you do). There are as many vaccinations out there as there are cattlemen/women, but all of them are not necessarily needed for your particular region. Assuming it is not required by state law, if you have an abundance of elk (no idea of how far they roam) or deer in your local area, I would make sure that Brucellosis was something I vaccinated for because they can infect your herd. As far as how you implement a health program - talk to your vet, decide what you're going to use (killed vs modified live), decide what the appropriate time to vaccinate is (killed vaccines can be given anytime, but that is not the case for MLV), find out when your heel fly season is so you know when to Warbex, run them through the chute and vaccinate/Warbex/worm when and as needed. Your vet should be able to show you how to do it or, if you prefer, he/she can vaccinate your cattle for you until you gain a little more experience and are comfortable with performing the procedures yourself.
PS I am not a trusting sort of person - so before I gave this kind of trust to a mentor, I would take a very long, very hard look at his/her cattle - as well as what kind of health problems, if any, he/she was dealing with. Along the same lines - before I settled on a vet, I would talk to as many people as I possibly could - including the vet's, and get references. Those talks would include ALL of the vets in at least a 30 mile radius (yes, I will haul my animals for quality service), which ones they had had dealings with, which ones they preferred (and why), as well as which ones they avoided (and why).
