by the nose

using an intranasal vaccine can help provide effective immunity at the spot where it is estimated 95% of infections enter the body - a new vaccine called Onset allows vaccination for IBR/PI3/BRSV/BVD without an injection and sidesteps the problem of 'maternal antibody interference'(protection passed to the calf from the dam’s milk that can prevent an immune response to vaccination) because of the vaccination site of the nasal mucosa.

i like the idea of this approach and the newer research showing that even calves right at birth have a fully competent immune system ready without worrying about the colostral antibodies will be very useful in helping calves get off to an even better start.
