The evaluation of the antitumour effectiveness of an anticancer vaccine (AV) based on sarcoma 37 tumour cells and Bacillus subtilis 7025 glycoprotein complexed with the fullerene C60 physically sorbed or chemically attached to aerosil was the aim of this work. It was established that the use of fullerene C60 for AV modification leads to the improvement of the antitumour properties of the vaccine.  Immunological investigations evidenced the stimulation of lymphocytes and the cytotoxic activity of peritoneal macrophages and an increase in the level of antibodies to sarcoma 37 antigen production. Hence, it may be concluded the modification of cancer vaccines with this nanomaterial significantly increases their antitumour effectiveness.
