FIELD: medicine, pharmaceutics.
SUBSTANCE: invention discloses compositions for inducing an immune response in a patient, containing a combination of two or more monovalent conjugates wherein each of the monovalent conjugates contains a carrier protein N19 conjugated with a saccharide antigen of the serogroups A, C, W135 or Y Neissera meningitides. A molecule of the carrier protein in the monovalent conjugate is preferred to be conjugated with more than one molecule of the saccharide antigen. Besides, the invention discloses a multivalent conjugate for inducing an immune response in a patient, containing two or more antigen-different saccharide antigens of the serogroups A, C, W135 or Y Neissera meningitides conjugated with the carrier protein N19. The compositions may contain one or more said monovalent conjugates and one or more said multivalent conjugates. The invention shows applicability of the multivalent conjugate and compositions in preparing a medicine for enhancing the immune response in a patient.
EFFECT: compositions used under the invention elicit much stronger and fast immune response and exhibit lower reactogenicity for a patient.
