Abstract: An inactivated whole-virus influenza vaccine may have its antibody-inducing ability is maintained or enhanced and may cause fewer side reactions. A method for preparing an inactivated whole-virus influenza vaccine may use an embryonated chicken egg method, including subjecting a virus solution including a whole influenza virus collected from embryonated chicken eggs to a hypotonic treatment.

Abstract: Provided are an adjuvant useful for preparing a vaccine having high efficacy and high safety, and a vaccine composition comprising the adjuvant. The adjuvant comprises a peptide nucleic acid to which a cell penetrating peptide is bound.

Abstract: A mucosal adjuvant may have high mucosal immunogenicity and high safety and be useful in the preparation of mucosal vaccines, and a mucosal vaccine composition may include the same. Such mucosal adjuvant may include TGDK. A method for preparing the mucosal vaccine composition may include mixing TGDK with an immunogen.

Abstract: An inactivated influenza vaccine may have high immunogenicity and may be produced by method including performing inactivation treatment using formaldehyde including treating a virus solution containing an influenza virus collected from a host with ?-propiolactone in advance. The inactivation treatment using formaldehyde may be performed by adding formalin to the virus solution at a final concentration of 0.005 to 0.015 vol %.

Abstract: Provided is a seasonal influenza vaccine having a higher efficacy than a split vaccine. A seasonal influenza vaccine which induces virus-specific antibodies in the nasal mucosa, comprises inactivated whole influenza virus particles as an active ingredient, and is to be administered intradermally at dose per administration of 15 ?g HA or more per strain as antigen.

Abstract: Provided is a pharmaceutical agent for enhancing absorption efficiency of a drug through the mucosal epithelial layer. A pharmaceutical agent for transmucosal administration comprises as an active ingredient a drug compound to which a podocalyxin targeting molecule is bound.

Abstract: Disclosed is a novel method for measuring haemagglutinin of an influenza virus, which can construct an assay system in a shorter period of time than a sandwich immunoassay method using two kinds of anti-haemagglutinin antibodies. The method for measuring haemagglutinin of an influenza virus is achieved by a sandwich immunoassay method comprising sandwiching the haemagglutinin between a lectin which binds to the haemagglutinin but does not bind to an antibody, and an anti-haemagglutinin antibody which undergoes antigen-antibody reaction with the haemagglutinin.
