You wont...........it will all catch up and much quicker than you expect !!!!!!! No goatkeeper is ever without a part bottle of vaccine.............goes with the territory.
Also don't forget you also need a bottle of Vecoxan as well...........give the kids a dose at 4 weeks approx..........to prevent coccidiosis. This is almost certainly going to be an issue this year wuith all the wet weather. This is administered as an oral dose, not injected.
Cocci rarely shows any symptoms in kids...........the first you will know about it...........dead kids
