In my area, we vaccinate for 8 way blackleg, rabies, IBR-PI3-BVD-BRSV, occasionally H. somnus. Bulls do not get vaccinated for lepto, since in Canada it prevents semen collection. They are also dewormed/deloused etc as required on a per farm basis. Timing on vaccination for the bull is not critical, but I don't recommend vaccination within the month prior to breeding season, since it could impair fertility if there is a reaction.
