My cows were vaccinated with "triangle" (the contents of which I am not entirely sure other than it is lepto/vibrio) last May. They are due to start calving Feb 25th. Would it be a good idea to give them a booster now or would it be just as good to wait until May? I might add that the snow is really deep where I am located and May seems a much better alternative to me.<br>Thanks for helping.
