Traditional vaccine approaches focusing on inducing neutralizing antibodies against DENV structural antigens have shown limitations and, under certain conditions, may also worsen infection through antibody-dependent enhancement (ADE) of infection. More recently, increasing evidence has highlighted the importance of T cell-mediated immunity and anti-non-structural protein 1 (NS1)-specific responses in suppressing DENV replication and reducing disease severity. DENV NS1, however, is known to be associated with severe dengue pathologies. In this context, immunization against NS1 offers a strategic advantage by eliciting immune responses that may contribute to early control of virus replication while simultaneously mitigating NS1-mediated vascular pathology. A vaccine delivery platform that would stimulate protective immune responses yet avoid the potential pathologic effects of NS1, hence, is needed.\n                    <jats:italic>Bacillus subtilis<\/jats:italic>\n                    spores antigen delivery platform stands out as a promising platform for its safety, stability, and inherent adjuvant properties.
