A Fully Synthetic Vaccine Consisting of a Tumor‐Associated Glycopeptide Antigen and a T‐Cell Epitope for the Induction of a Highly Specific Humoral Immune Response

On target: With the fully synthetic vaccine 1 consisting of a tumor-associated sialyl-Tn glycopeptide antigen from the epithelial mucin MUC1 and a T-cell epitope from ovalbumin, a strong, highly specific immune response (IgG) directed against the glycopeptide antigen was induced in a mouse thereby realizing the most important requirement for the development of synthetic vaccines for the initiation of the body's own immune defense against tumors.
