This course provides an in-depth exploration of virus structure, virus replication, and the mechanisms of interaction with the host. It emphasizes the practical application of molecular techniques in virology research. The curriculum covers traditional virology, virus diagnostic technologies, and hands-on training in vaccine development. The goal is to equip students with a solid foundation in virological theory and the ability to apply molecular techniques. Through this course, students will enhance their independent research and innovation skills, applying their knowledge of molecular virology to vaccine development and related biomedical fields.
