1. A composition for inducing an immune response in an individual against Norovirus, the composition comprising a therapeutic amount of a P-particle in a suitable sterile, nontoxic physiological medium, wherein the P-particle comprises Norovirus capsid P domain monomers selected from the group consisting of SEQ ID NO:
- 2, a P protein, a P protein without a hinge, a P protein with a hinge and a cysteine linked to the end of a P1 subdomain of the P protein, and mixtures thereof.

Abstract
Norovirus capsid protein monomers having only the P domain, and not the hinge or S domain, can assemble spontaneously into an icosahedral form herein called the P-particle. Factors affecting the formation and stability of the P-particle, as well as providing methods for diagnosing and treating Norovirus-infected individuals and creating a vaccine for prevention of Norovirus infection are presented.

- 3. A method of inducing an immune response in an individual against Norovirus, the method comprising the step of orally or parenterally administering to an individual at least one immunologically effective dose of a composition comprising an isolated P-particle, the P-particle comprising a P protein from a Norovirus strain recombinantly expressed or synthesized from a cDNA comprising a fragment of the cDNA sequence of the capsid protein of the Norovirus strain, and a pharmaceutical carrier, wherein the dose is effective in inducing the immune response in the individual.
- 7. An isolated P-particle comprising capsid P domain monomers from a Norovirus strain.
