Method of removing viruses from liquid composition containing factor vii

Invention discloses versions of a method of cleaning a liquid composition which contains recombinant factor VII from viruses. The composition to be cleaned contains at least 5% recombinant polypeptide of factor VII in activated form. Cleaning is carried out using a nanofilter with pore size of at most 80 nm.

Use of inactivated intact virus of compatible subtype to obtain acellular vaccine and method of treating hiv infection

Invention relates to biotechnology, virology and medicine. Vaccines can be used to treat individuals chronically infected with HIV by inducing a protective cell-mediated response in these individuals against the same HIV subtype which was used to make the vaccine. Invention can be used in medicine.
