IMMUNOGENIC COMPLEX FORMED BY VACCINAL ANTIGENS ENCAPSULATED BY NANOSTRUCTURED MESOPOROUS SILICA

The present invention relates to an "immunogenic complex" product comprising an adjuvant characterized by solid particles of highly ordered nanostructured mesoporous silica, preferably SBA-15 antigenic silica of various natures encapsulated in said adjuvants. The immunogenic complex of the present invention allows the presentation of the antigen that composes it to lymphocytes in a safe, gradual and prolonged way that leads to a more efficient immunological memory, increases antigen immunogenicity and improves antibody production. This ensures efficient immunological protection with lower antigen amounts and / or fewer repeat vaccine doses. Furthermore, the characteristics of the immunogenic complex of the present invention promote effective homogeneous induction of immunity in "good and bad responders" individuals.
