Vaccinating for IBR but still have carrier animals

martinnn1997 · 2025-05-29 16:10:09

Hi all, Just wondering if anyone has come across the same. So I've been vaccinating my herd for IBR (live vaccine) for the past 6 year's. However, my milk results are telling me I still have carrier animals. Has anyone else come across this before?

Vaccinated animals can show up as positive for carriers as I understand , you might need a blood test to distinguish between the two.
