Abstract
Development of a vaccine that can simultaneously induce effective mucosal immunity and systemic immunity is an ideal goal to prevent mucosal pathogenic infections. The digestive tract has many sites for inducing mucosal immunity, including the mouth, stomach and small intestine. An ideal oral viral vaccine can not only induce better local and distal mucosal immunity, but also produce better systemic immunity. The oral viral vaccine has also attracted much attention because of its painless vaccination, self-administration and other advantages. Due to the complexity of human digestive tract environment and mucosal immunity, only three oral attenuated live vaccines have been successfully marketed for human use. This review summarizes the characteristics of gastrointestinal mucosal immunity, the current types and research status of oral viral vaccines, and the challenges faced by oral viral vaccines, with the hope to facilitate the research and development of oral viral vaccines for human use in China.
