Unraveling Mucosal Immunity

This chapter explores the intricacies of immune responses, especially the role of memory cells in nasal-associated lymphoid tissue and their impact on vaccine efficacy. It discusses challenges faced by mucosal vaccines, particularly the influence of preexisting immunity in adults versus children, while examining the dynamics of infection persistence. The conversation further investigates the interactions between systemic and mucosal immunity, highlighting the significance of the nasal cavity in protecting against infections and shedding light on transmission mechanisms of various viruses.
