Lessons learned emphasize the need for coordinated vaccination campaigns, scientific evaluation of disease control strategies, and strengthening surveillance and post-vaccination monitoring to achieve long-term disease eradication goals. 6 Future Directions in Goat Vaccine Development 6.1 Integration of genomics and proteomics The integration of genomics and proteomics is poised to revolutionize goat vaccine development by providing comprehensive insights into pathogen-host interactions and identifying potential vaccine targets (Qin et al., 2024a). Genomic approaches, such as reverse vaccinology, allow for the high-throughput screening of pathogen genomes to identify antigens that could serve as effective vaccine targets (Seib et al., 2012). Proteomics complements this by characterizing the host's immune response to these antigens, thereby facilitating the identification of immunogenic proteins that can be used in vaccine formulations (Adamczyk-Popławska et al., 2011). This combined approach not only accelerates the discovery of new vaccine candidates but also enhances our understanding of the molecular mechanisms underlying vaccine efficacy (Mora and Telford, 2010). 6.2 Role of artificial intelligence and machine learning Artificial intelligence (AI) and machine learning (ML) are increasingly being utilized to streamline the vaccine development process. These technologies can analyze vast datasets from genomic and proteomic studies to predict potential vaccine candidates and optimize vaccine design (Russo et al., 2020). AI-driven systems biology approaches can model immune responses and predict the efficacy of vaccine candidates, thereby reducing the time and cost associated with traditional vaccine development pipelines. The use of AI in vaccine development is expected to lead to more precise and effective vaccines, as it allows for the rapid identification and testing of novel antigens (Rawal et al., 2021). 6.3 Policies and international collaboration The advancement of goat vaccine development also hinges on effective policies and international collaboration (Donnarumma et al., 2016). The establishment of regulatory frameworks that support the use of in silico trials and AI-driven vaccine development is crucial for the acceptance and implementation of these technologies (Qin et al., 2024b). Furthermore, international collaboration can facilitate the sharing of genomic and proteomic data, as well as best practices in vaccine development, thereby accelerating the development of vaccines for goat diseases that have global significance. Collaborative efforts can also help in addressing challenges such as antimicrobial resistance by promoting the development of vaccines as alternatives to antibiotics (Kaushik et al., 2023). 7 Concluding Remarks The development of vaccines for major goat diseases has shown promising advancements across various studies. The Mycobacterium tuberculosis SO2 vaccine demonstrated significant protection against tuberculosis in goats, reducing lesion severity and bacterial load compared to controls. Similarly, the indigenous vaccine for Johne's disease showed superior efficacy in improving physical conditions and reducing mortality and morbidity in goats compared to commercial vaccines. The multivalent Capripoxvirus-vectored vaccine effectively protected against multiple viral infections, including sheeppox, goatpox, and Rift Valley Fever, highlighting its potential for broad-spectrum protection. Additionally, the ARRIAH live attenuated vaccine provided complete protection against peste des petits ruminants (PPR) without clinical signs, indicating its efficacy and safety. These findings underscore the potential of novel vaccine strategies, such as multi-epitope and adenoviral-vectored vaccines, in enhancing immune responses and providing robust protection against goat diseases. The advancements in vaccine development for goat diseases have significant implications for both policy and research. Policymakers should consider supporting the implementation of these vaccines to improve livestock health and productivity, particularly in regions heavily affected by these diseases. The success of indigenous vaccines and multivalent formulations suggests a need for policies that encourage the development and distribution of region-specific vaccines. Furthermore, research should continue to focus on optimizing vaccine
