Mucosal vaccination has the potential to revolutionize immunization and has several benefits over other conventional parenteral vaccination routes, including enhanced mucosal immune responses and ease of administration. However, the regulatory environment for mucosal vaccines is complex and diverse, necessitating a detailed understanding of the requirements for their development, approval, and deployment. This section offers an in-depth examination of how a regulatory framework is constituted around mucosal vaccinations. This chapter starts with an overview of mucosal vaccination and its importance in the fight against infectious diseases. It proceeds to explore various regulatory policies provided by leading regulatory agencies, which include the Food and Drug Administration (FDA), European Medicines Agency (EMA), and World Health Organization (WHO). It gives a comprehensive look into what makes the control of mucosal vaccines different from others, such as immunological mechanisms, administration routes that are best, formulation stability, and safety assessment. The chapter presents critical insights and best practices for navigating the regulatory landscape effectively through analysis of diverse case studies representing successful regulatory approval processes for mucosal vaccines. Also, it talks about future perspectives on emerging technologies, regulatory adaptations to accommodate evolving scientific advancements, and the necessity for global collaboration to accelerate the development and regulatory approval of mucosal vaccination strategies. The main purpose of synthesizing contemporary regulatory knowledge and giving practical advice in this chapter was to create a useful tool for investigators, producers, and regulatory officials who are working on mucosal vaccines. In the long run, this work will help advance global public health programs.
