Any available vaccine which reduces my chances of infection, even to "58%", is overwhelmingly worth receiving. Add the additional benefit of reducing the seriousness of the potential illness, and avoiding the vaccine becomes almost ridiculous. Then figure in some factor with which vaccinated individuals are less likely to pass along the illness to others, and ridiculous is reduced to just plain stupid, if not near criminal.

As it is, flu or not, the airlines can barely clean the lavs, much less effectively "disinfect" the cabin. "Sani-wipes"? Some modest local protection, but offer no defense against the most common vector, the moisture-laden exhalations of fellow passengers traveling in the nearly-sealed aluminum cocoon of the a/c.
