You really, really should get a good book or two on keeping goats healthy, PLUS be in contact with a good Large Animal or Livestock Vet. Goats are a bit different, and even a lot of farm vets, who know horses and cows, don’t know much about goat medicine.
But at a minimum, you’ll have to:
Decide if you’re going to re-vaccinate your goats annually. We do, but there’s a good argument to be made if your goats are isolated from other goats, aren’t going to shows, no other goats are coming on the farm, that perhaps you don’t need to bother with vaccinating them. Your call.
