Vaccination protocols

What is everyone's suggested vaccination protocol for new calves? What do you usually start them off on & why? Also tell area of country so we can get a better idea on why or what you are doing.
Thanks, figured this would be a good learning experience for some of us & also maybe teach some of us old dogs new tricks! (dog)

We use 7 way at birth, and at branding (usually 3-4 months later.)  At weaning they get Cattlemaster 4.  The mother cows are vaccinated with Scourgaurd 3KC before they calve.  We use a modified live Lepto-Vibrio-IBR before breeding.

Do you use BOSE or MUSE? We use those at birth & then barguard  99.
