We have the ability to make Tuberculosis not exist and have for half a century.

Please tell me more. My knowledge about this must be very outdated.

There are a lot of things that are really only failing for a lack of distributing ressources. But Tubercolosis (where our once widely used vaccine was mostly ineffective in eradicating it and the treatment is complicated and long requiring monitoring of each patient because of the possibility of secondary infection from the antibiotics or organ damage) is not what comes to my mind first, second or for quite a while.

In fact in both cases research is ongoing in search for more effective vaccines and easier treatments (primarily for shorter treatment periods as well as against the multiple antibiotic resistences), because our tools today are not actually up to the task.
