I haven't heard of it, but #1, get your cattle's immune system up and many of these things go away on their own.
Enhanced immune system is everything, in fact, without it no vaccine works as well.
Sounds like vaccinating before the sickness it should help, doesn’t sound like it will cure anything but is more a preventative.
Again, another needle at 10 to 14 days after the first one, and 3 to 5 weeks apart for Pasteurella.
