摘要

The subject of the invention is an influenza virus haemagglutinin antigen, an influenza vaccine comprising said antigen, a method of producing said antigen, and use of the antigen as stated above to produce an influenza vaccine. The invention involves a new method of producing said antigen, suitable for use in a vaccine. The outcome as stated in the invention leads to obtaining a highly immunogenic antigen, which does not require contact with the whole virus but just haemagglutinin. The vaccine as described in the invention does not contain the virus or its parts, does not contain cells coming from other organisms or their parts, but only purified haemagglutinin antigen.
