Introduction

Vaccination has undoubtedly been one of the most transformative achievements in the history of medicine, effectively preventing and mitigating a wide range of infectious diseases that once plagued humanity. For centuries, vaccines have been administered through intramuscular or subcutaneous injections, primarily targeting the development of systemic immunity. While these traditional vaccination methods have been highly successful, they often overlook a critical aspect of our body’s defense mechanisms: mucosal immunity [1,2]. Mucosal surfaces, including the respiratory, gastrointestinal, and genital tracts, serve as the frontlines of our body’s defense against invading pathogens. These surfaces are the primary points of entry for many infectious agents, making them strategically significant in the battle against diseases. However, until relatively recently, the potential of mucosal immunization strategies remained largely untapped in the field of vaccinology. In recent years, a growing body of research has begun to shed light on the extraordinary potential of mucosal immunization as a means to enhance our defenses against infectious agents. This paradigm shift in vaccine development and delivery holds promise for revolutionizing the way we protect individuals and populations from diseases [3-5]. This exploration into the future of vaccination delves into the emerging field of mucosal immunization strategies. It aims to provide a comprehensive overview of the opportunities and challenges associated with harnessing mucosal immunity for vaccine development. Through this examination, we will uncover the innovative approaches, potential benefits, and groundbreaking research that are paving the way for a new era in vaccinology. This journey into the future of vaccination begins with an exploration of the mucosal immune system itself, highlighting its unique features and importance in our body’s defense mechanisms. It then delves into the various mucosal vaccination strategies, such as intranasal, oral, and intravaginal vaccination, shedding light on the distinct advantages and complexities of each approach. Furthermore, we will examine the current state of mucosal vaccine research, focusing on promising candidates targeting a spectrum of infectious diseases, including influenza, HIV, and the novel coronavirus, SARS-CoV-2. We will also address the critical considerations of safety, efficacy, and regulatory pathways, which are paramount to ensuring the successful translation of mucosal immunization strategies from the laboratory bench to clinical applications [6-8].
