NJH, Mayo and every pulmonologist I know recommends all applicable vaccines for MAC and Bronchiectasis patients, subject to suitability for their individual health profile.

As my primary doc once pointed out to me "A little cold gives you bronchitis, and you end up sick. Do you really want to risk getting the flu or pneumonia?"

So, every year, I get my recommended injections, knowing I am going to feel poorly for a few days because my immune system overreacts, but I have avoided getting the respiratory flu for over 10 years, and I haven't had pneumonia since I got treated for MAC and started getting the vaccine as recommended, in spite of being out and about in the community.
