Vaccines that specifically induce immunity against bacterial pathogens are required. Here the authors produce and characterize an intranasal liposomal vaccine against a peptide antigen from Streptococcus pyogenes and show that it induces a strong mucosal IgA response lasting for over one year, and that protection is dependent on cellular immunity mediated through IL-17, macrophages and neutrophils.
