You need to define your goals and then plan your vaccination protocol
Suggest you provide the following info and then talk with your veterinarian.
Your actual cattle - age, breed, gender, bred or open, size, etc
Your final goal - feeding out, cow calf, etc
Your climactic conditions
Your breeding schedule
And a whole bunch more that I have missed and others will pitch into the ring.
No such thing as a one shot wonder or silver bullet.
So, my best advice would be to sit down and discuss this with your veterinarian or local farm rep - someone who actually has a schmick about cows - especially cows in YOUR part of the world - and then decide upon your protocol.
No sense in someone from Texas or Alabama telling you how to vaccinate when you are in northern Alberta - or vice versa.
