This is a very interesting discussion. Thank you to those who participated. I agree with Sue that there just isn't enough monry available for the research needed to develop a vaccine (assuming one is possible) for our comparatively small number of patients

It is important to remember that the bacteria is around everyone, but the vast majority of people do not become infected. One must have a problem with the lungs making them unable to clear any inhaled bacteria. For most of us, the problem is bronchiectasis. If we had a cure for that, we would be like the rest of the world and be able to inhale and exhale MAC or any other mycobacteria or bacteria and be just fine. We could even sit in a hot tub.
