After seeing studies like this, and how the shingles vaccine reduces dimensia, I have become increasingly convinced that it’s bad to get almost any disease, even transiently. I used to think that it was kind of good to train your immune system (kind of whatever doesn’t kill you makes you stronger). I no longer believe that. I believe that diseases often cause unknown effects and it’s better to avoid disease entirely, that vaccines are actually more beneficial than current studies show in this regard, and new universal vaccines to prevent the common cold and flu will likely have significant health span improvements over time beyond the acute prevention of symptoms.
