The external part of the eye shares mucosa-associated common characteristics and is an obvious entry site for foreign Ags. We assessed potential eyedrop vaccination effective delivery vaccines against viral or bacterial infection in mice. Both OVA-specific IgG Ab serum IgA mucosal compartments were induced by eyedrops OVA with cholera toxin (CT). Eyedrop influenza A/PR/8 virus (H1N1) both virus-specific systemic responses protected mice completely respiratory virus. In addition, attenuated...
