INFLUENZA VACCINES CONTAINING HEMAGGLUTININ AND MATRIX PROTEINS

摘要

An immunogenic composition comprising influenza virus haemagglutinin and matrix proteins. These may be from influenza viruses grown in cell culture rather than eggs. The matrix protein may be a fragment of a full-length viral matrix protein e.g. a matrix M1 fragment with a molecular weight of less than 2O kDa. The composition may be a subunit vaccine comprising purified surface glycoproteins.
