What vaccinations did Robert Koch develop?

Robert Koch is primarily known for his contributions to bacteriology rather than the development of vaccines. He is famous for identifying the causative agents of tuberculosis (Mycobacterium tuberculosis) and cholera (Vibrio cholerae), but he did not develop specific vaccinations for these diseases. Instead, his work laid the foundation for later advancements in immunology and vaccine development by establishing the germ theory of disease. Vaccines for tuberculosis and cholera were developed after his time, building on his research.
