Gerda, my getting sick in 1999 was not in any way related to the vaccine I took in the early '80's. Pneumonia was the first time I suffered in 1999; then I had at least three or four more illnesses that same year, though, not pneumonia specifically. In fact, it was several years later that I had pneumonia again, after I left that job in 1999.

However, having had pneumonia twice gave me an immunity to a recurrence. I have been well since that last pneumonia in the early 2000's.

As a child I had hepatitis A, which is due to bad germs. I must have been childishly ignorant of cleanliness. Other than carelessness about germs, I have RARELY been sick with any major outbreak. And YES, I am grateful about the health improvement.
