FIELD: medicine.
SUBSTANCE: invention refers to biotechnology and virology. What is presented is a method for producing viral-like influenza virus particles (IVP) in a plant or a part thereof. The method involves the expression of a new influenza virus protein HA in plants and purification thereof. The invention also aims at IVPs containing the influenza virus protein HA and herbal lipids. The invention also refers to nucleic acids coding an improved influenza virus HA, as well as to vectors. The IVPs can be used in developing the influenza vaccines or for the treatment of existing vaccines.
EFFECT: presented group of inventions can be used in medicine.
