This study evaluates an intranasal subunit vaccine based on albumin-antigen fusion to induce systemic and mucosal immunity. Using the HSA/hFcRn mouse model, the vaccine elicited robust systemic IgG and mucosal IgA responses, providing protection against SARS-CoV-2 and influenza A virus. The model allowed precise evaluation of FcRn-mediated antibody transport and persistence.
Albumin-based intranasal vaccination induced strong systemic and mucosal antibody responses and superior protection compared to standard mRNA and non-albumin nasal vaccines.
Humanized double Knockin HSA/hFcRn mouse model developed by genOway, expressing human serum albumin and FcRn for accurate pharmacokinetic and immunogenicity studies.
