An immunological composition comprising influenza virus haemagglutinin and matrix proteins. These may be from influenza viruses grown in call 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 20 kDa. The composition may be a subunit vaccine comprising purified surface glycoproteins. |
