Provided herein are recombinant fusion polypeptides comprising one or more antigenic peptides (e.g., fused to a PEST-containing peptide) from cancer-associated proteins. The antigenic peptides can comprise one or more or all of an antigenic peptide comprising a recurrent cancer mutation, an antigenic peptide comprising a heteroclitic mutation, or an antigenic peptide fused to a ubiquitin protein. For example, provided herein are recombinant fusion polypeptides comprising two or more antigenic peptides (e.g., fused to a PEST-containing peptide), wherein each antigenic peptide comprises a recurrent cancer mutation, and wherein at least two of the antigenic peptides are fragments of the same cancer-associated protein. Also provided are nucleic acids encoding such fusion polypeptides, recombinant bacteria orstrains comprising such fusion polypeptides or such nucleic acids, and cell banks comprising such recombinant bacteria orstrains. Also provided herein are methods of generating such fusion polypeptides, such nucleic acids, and such recombinant bacteria orstrains. Also provided are immunogenic compositions, pharmaceutical compositions, and vaccines comprising such fusion polypeptides, such nucleic acids, or such recombinant bacteria orstrains. Also provided are methods of inducing an anti-tumor-associated-antigen immune response in a subject, methods of inducing an anti-tumor or anti-cancer immune response in a subject, methods of treating a tumor or cancer in a subject, methods of preventing a tumor or cancer in a subject, and methods of protecting a subject against a tumor or cancer using such recombinant fusion polypeptides, nucleic acids, recombinant bacteria orstrains, immunogenic compositions, pharmaceutical compositions, or vaccines.
