Special Topic _ The development trend of biotechnology industry in the postdouble epidemic era

The five-day event provided IAVT students with valuable insights into the principles and practices of veterinary vaccine development, with a particular focus on avian species. The lectures began with an overview of avian diseases and the structure of the global poultry industry, highlighting the importance of vaccine innovation in disease prevention and food security. The speakers then delved into various vaccine types, including live attenuated and vector vaccines, explaining their mechanisms, advantages in inducing strong immune responses, and strategic use in preventing major poultry diseases. They further explored the characteristics and practical applications of killed and subunit vaccines, which offer high safety profiles and targeted immunity but require careful formulation and adjuvant support to achieve full efficacy. Emphasis was also placed on key formulation components such as adjuvants, stabilizers, and other excipients, which play a critical role in enhancing immune response, ensuring vaccine stability, and extending shelf life. The discussion extended into the industrial perspective, outlining the process of veterinary vaccine development in the pharmaceutical sector—from early-stage research and antigen design, through preclinical evaluation and regulatory approval, to large-scale production and distribution. Throughout the sessions, students gained a comprehensive view of the technical, scientific, and commercial considerations involved in bringing effective animal vaccines to market. The lecture series concluded with student presentations and an engaging discussion session, providing a platform for participants to apply their knowledge and exchange ideas directly with the visiting experts.
