At the primary sites of pathogen infection, mucosal vaccines have the potential to incite strong protective immune responses.
Induction of adaptive immunity at mucosal locations, involving secretory antibody responses and tissue-resident T cells, has the potential to stop an infection from starting in the first place, rather than just preventing infection and warding off the onset of disease symptoms. The major developments in injectable vaccines, such as adjuvanted subunit antigens,RNA, and DNA vaccines, have not yet been translated into licensed mucosal vaccines, which currently only include live attenuated and inactivated whole-cell preparations. Despite the fact that there are many effective mucosal vaccines in use. The development of mucosal vaccines depends on the discovery of secure and efficient mucosal adjuvants, together with cutting-edge antigen discovery and delivery techniques.
