Because unvaccinated stock may be infected with lungworm and as a result produce very high levels of pasture contamination that could overwhelm the immunity of the vaccinated animals. However, it is not good to continually keep calves on clean pasture eg aftermath. Better to start calves off on permanent pasture that was grazed by calves or adults last year.
