Abstract
The present invention provides a vaccine for enteroviruses. In view of the structure of enteroviruses, particularly VP0's cleaving VP2 and VP4, it was discovered that said cleaving affects immunogenicity. In other words, it is believed that designing a vaccine including a large amount of VP2 and VP4 as polypeptides which exhibit immunogenicity leads to providing a vaccine which exhibits high immunogenicity. Polypeptides including VP1, VP2, VP3, and VP4 derived from an enterovirus are produced, and these polypeptides are confirmed to have a high effect as an immunogen against enteroviruses.

Abstract
Provided is an antigen composition, pertaining to human herpes virus 6B (HHV-6B), which can be stably supplied in a large amount. Also provided is a vaccine including this antigen composition. Also provided is a method for producing this antigen composition. HHV-6B antigen tetrameric complexes including gH, gL, gQ1, and gQ2 among the surface proteins of HHV-6B are used as the antigen composition. The HHV-6B antigen tetrameric complexes make it possible to provide an antigen composition which can be stably supplied in a large amount. Because the antigen composition can be stably supplied in a large amount, it is possible to stably supply vaccines and pharmaceutical compositions including this antigen composition, which is industrially advantageous.

Abstract
The present invention relates to an adjuvant, which is a layered double hydroxide and is obtained from a compound represented by general formula (I) in the Specification. Because the layered double hydroxides in the present invention are conjugates with an inorganic ion selected from light metals, it is thought that adverse reactions of a living body when an immune composition comprising an adjuvant according to the present invention is administered to the living body will be minimal. Because there are countless combinations of divalent cations, trivalent cations and anions in layered double hydroxides, it is possible to manufacture a layered double hydroxide suited to the use thereof.

Abstract
Antibodies (Abs) play roles in protection against influenza. Neutralizing Abs either inhibit the binding of hemagglutinin (HA) to cellular receptors or prevent the conformational change of HA induced by lowpH. The former Ab binds to the regions near the sialic acid-binding pocket on the globular head formed by HAl and generally shows narrow strain specificity. The latter Ab binds to the stem region formed mainly by HA2 and shows broad strain specificity. We isolated a broadly neutralizing Ab against H3N2 viruses. X-ray analysis of the HA/Ab complex indicated that the Ab binds to the valley formed by two neighboring HA monomers at the side of the globular head. The Ab shows neutralizing activity by preventing the conformational change of HA induced at low pH.
