Just about to give some lambs their 2nd dose of Heptavac.

We've recently bought 2 new lambs and I can't honestly remember if the seller said they'd had both doses yet. If they have and I give them a third one will it hurt them?

I don't think you would have any problems. I was always told if you are unsure then give them another course.

If you do vac them again you'll need to do the 2 new lambs again in 4-6 weeks
