Cover Story: Considering that SARS-CoV-2 is mainly mucosally transmitted, a therapy administered via this same route may represent a desirable approach to fight SARS-CoV-2 infection. Experience over the past few decades has clearly demonstrated that a shift from traditional needle-based to needle-free immunization can overcome a number of limitations. Therefore, in this review, we highlight the potential of using genetically modified probiotics to express SARS-CoV-2 proteins with the aim of developing candidate oral vaccines that are capable of stimulating immune responses in the gut and lung to fight COVID-19. Indeed, the crosstalk and reciprocal interaction of the gut and lung mucosa (gut–lung axis) is mediated by immune cells moving between the two districts via the bloodstream and the lymphatic ducts, leading to modulation of the immune response at both sites.
