Recent advancements in animal vaccine development have significantly contributed to improving animal health and controlling zoonotic diseases. Novel vaccine technologies, such as recombinant vector vaccines, mRNA-based platforms, and nanoparticle delivery systems, are gaining momentum due to their enhanced efficacy, safety, and rapid development timelines. These innovations are particularly impactful in managing outbreaks of economically significant diseases such as Foot-and-Mouth Disease (FMD), Avian Influenza, and African Swine Fever. In addition, multivalent vaccines are being developed to target multiple pathogens simultaneously, reducing the need for repeated administrations and improving compliance among livestock producers.

Current research also emphasizes the role of adjuvants and immunomodulators in boosting immune responses in animals. Regulatory efforts are aligning with these technological advancements to ensure faster approval and distribution of safe vaccines. Additionally, the use of DIVA (Differentiating Infected from Vaccinated Animals) strategies is facilitating better disease surveillance and control. These developments mark a progressive step toward sustainable livestock production, improved food security, and public health protection. The Journal of Animal Research and Veterinary Science continues to track these breakthroughs, underscoring their significance in global veterinary medicine.
