The only problem with your comparison is that all of the diseases you mention, except tetanus, are infectious person-to-person, which MAI and the related infections are not. Tetanus was included in vaccine research because it was 99% fatal if you got it. Again, MAI is not.

@windwalker Terri - unfortunately, even when you add together the number of people with bronchiectasis and Cystic Fibrosis, we was talking about less than 1/2 of 1% of the population, so the combination - low occurence, not fatal, and not contagious, keep this research from rising to the top of the priority list.

Sad, but unfortunately true.
