And I wonder if you could just sort of talk us through some of the ecological costs of, of not using a vaccine, of taking the old-fashioned approach.

Yeah.

I mean, I was gonna back up Helen there.

She made some brilliant points.

We, we often see farms that have used routine treatments for years and years, maybe 20 years, and they move to the vaccine, and you see huge animal health benefits that weren't really obvious before the switch.

Whether that's resistance or whether that's better control and better timing rather than hitting them with a treatment a little bit too late is, is impossible to say.

But I also wanted to back up the point about resistance and this feeds into the costs.

So Rob, what do you think the options are in terms of the profession kind of as a whole?
