On viruses

I was thinking about ergodicity in application to viruses like common cold, flue and like. I mean how "horizontal" probabilities (across population) correspond to "vertical" (temporal) probability for one person. I can only make experiments with one subject, so I performed two experiments.

1. It is said that flu vaccines makes it highly unlikely to catch the current flue. Across population. My experiment was 7 vaccinated consecutive years and 9 unvaccinated (and counting). When vaccinated, I had flue 6 times, and when unvaccinated, got it once.
2. Usually common cold virus used to make my life uncomfortable for ~4-6 days. Three years ago I infected myself with a probiotic bacteria for nose, and after my immune system coped (that took ~5 days of high fever), I no longer have 4-6 days cold, now typical virus symptoms take just 2 days, and then I have ~5 days of bacterial symptoms that are much milder and do not interfere with my work and active life.

Obviously if it works for me, there is no guarantee that it scales.
I just wonder if second experiment interferes with first..
