[QUOTE="Buck Randall, post: 1609701, member: 38590"] You're generally correct. The vaccine would potentially have some benefit to calves who did not get protective immunity from colostrum (10-20% in most herds). The problem with most injectable vaccines is that they are unnecessarily hard on calves at that age. Newer research in dairy calves has shown that vaccinating with most injectable vaccines is actually harmful to very young calves, as it produces more stress than it's worth. The one exception to this was C/D & T vaccine, which didn't set calves back. I would definitely avoid using 7 or 8 way clostridials or injectable modified live respiratory vaccines in newborn calves.
