Inactivated influenza vaccine adjuvanted with Bacterium-like particles induce systemic and mucosal influenza A virus specific T-cell and B-cell responses after nasal administration in a TLR2 dependent fashion

Altogether these results indicate that nasal BLP-SV vaccination induces IAV-specific T-cell and B-cell responses, both systemically and at the site of virus entry in a TLR2-dependent manner.
