This invention relates to an adjuvant composition containing at least one binding molecule for neutralizing influenza virus and a vaccine composition containing the same. The composition containing at least one binding molecule for neutralizing influenza virus is capable of increasing the effects of a vaccine, and can thus be used as an adjuvant, which increases an immune response upon vaccine administration, and is very useful in the prevention of diseases caused by viruses.

Provided herein are immunization regimens for inducing an immune response (e.g., an antibody response) against influenza virus. In specific aspects, the immunization regimens involve the administration of a chimeric hemagglutinin (HA), a headless HA or another influenza virus stem domain based construct (e.g., the HA stem domain or a fragment thereof) to a subject. In certain aspects, the immunization regimens also involve the administration of an influenza virus neuraminidase immunogen.

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.

Provided herein are engineered red blood cells expressing rare blood antigen group profiles, and methods of making use the same, are described. Also provided are recombinant reagent red blood cells that express or lack the expression of at least one protein (e.g., a blood group antigen) on its surface and uses thereof.

The present specification discloses recombinant nucleic acid constructs encoding an immunogenic multiepitope polypeptide comprising two or more polypeptides, recombinant nucleic acid constructs encoding at least two epitopes from two or more internal proteins of influenza virus, compositions comprising such recombinant nucleic acid constructs and methods of eliciting a T cell immune response against an influenza virus in a vertebrate using such recombinant nucleic acid constructs and compositions.
