Currently, mucosal infectious diseases are still a very high global health burden, but there are few effective vaccines to prevent mucosal-borne diseases. The development of mucosal vaccines requires the selection of appropriate antigens, delivery system strategies, and adjuvants to increase vaccine efficacy but limited studies have been conducted. The aim of this review is to describe the mucosal immune system, as well as the potential for the development of vaccines and mucosal adjuvants, and their challenges. The study was conducted by applying inclusion criteria for the articles, and a review was conducted by two readers with the agreement. It was known that mucosal vaccination is a potential route to be applied in future preventive efforts through vaccination. However, limited studies have been conducted so far and limited mucosal vaccination has been approved. New technological approaches such as material development involving nano- and micro-patterning are important to intensively open and investigate the potential area of development to provide better vaccination methods.
