Tetanus is much more common as a sequel to banding - but the first case of tetanus I ever saw was in one of my own steers, that I knife-cut two weeks earlier.
Lost a nice 5-month heifer to tetanus 2-3 years back... have no idea what her injury/exposure was - but since then, we've been using a polyvalent Clostridial bacterin with tetanus toxoid on ALL calves... and a booster!
Most calves get their initial dose at 2-3 weeks, then a booster 3-4 weeks later.
