INFLUENZA VIRUS-LIKE PARTICLES (VLPS) COMPRISING HEMAGGLUTININ

摘要

A method for synthesizing influenza virus-like particles (VLPs) within a pla nt or a portion of a plant is provided. The method involves expression of influenza HA in plants and the purification by size exclusion chromatography. The invention is also directed towards a VLP comprising influenza HA protein and plants lipids. Th e invention is also directed to a nucleic acid encoding influenza HA as well a s vectors. The VLPs may be used to formulate influenza vaccines, or may be used to enri ch existing vaccines.
