Standard advice is to booster 2 to 4 weeks after an initial vaccination, and then annually after that. A few folks booster twice for a total of three shots. Have you seen any data on how effective this is?

gcreekrch We have also bought in cows that were on a killed program. A couple died from BRD. [/quote said:Re homing cows can be incredibly stressful. Inforce 3 and mass medication on day zero for that kind.
I don't have any specific data for you, but the results are going to be extremely variable depending on what vaccines you're using and the condition of the cattle being vaccinated. For animals that have already developed immunity, the extra vaccination (especially modified live injectables) is only going to serve as an added stressor and drag on the immune system.Stocker Steve said:Standard advice is to booster 2 to 4 weeks after an initial vaccination, and then annually after that.

I've been trying to find literature on the efficacy of a killed vaccine that goes un boosted. As in, do you only get another 3 or 4 percent coverage, or if left un boosted does the coverage go to zero? I'm just curious as to the numbers but can't find any.
