Summary:
- This article discusses the ongoing "vaccine arms race" between livestock pathogens and the vaccines designed to protect against them. As new variants of livestock diseases emerge, existing vaccines become less effective, requiring the development of updated vaccines.
- The article explains that livestock pathogens can evolve and adapt quickly, often outpacing the ability of scientists to develop new vaccines. This constant race to stay ahead of evolving diseases is a significant challenge for the livestock industry.
- The article highlights the importance of continued research and innovation in veterinary science to ensure that livestock herds remain protected against emerging disease threats, which can have significant economic and food security implications.
