Since vaccines have ~nearly~ wiped out certain diseases, and since we as a population are no longer continually exposed to these germs, doesn't it seem that the vaccine itself loses it's effectiveness in the absence of the germs? This article posted here a few days ago got me thinking about this. http://www.ajc.com/health/content/me...h_vaccine.html
Does our immune system need the germs floating around amongst us to make either vaccines or natural immunity work correctly? Are there articles that talk about this specifically? Are there studies out there that involve this question?
This article also got me thinking about this too. http://www.vaccinationnews.com/rally/Meas100%25Vax.htm
The students in the outbreak were all vaccinated (I think, the article was not entirely clear) and the implication is that the vaccine "wears off" after 10 years. But weren't there preschool kids also affected? Perhaps it is not the vaccine that is wearing off, but rather as measles becomes more rare, the vaccine fails in more people or really does not work at all (gasp!) The way this article presented all the facts made it almost seem like the outbreak was a planned experiment. But regardless, I find this quite interesting.
