The author of this hypothesis is G A Rook (an immunologist). His paper is
entitled
Give Us This Day Our Daily Germs. Immunology Today. 19:113-116.
where he postulates that a lack of exposure to disease and dirt in childhood
- a practice we all seem to encourage so much in our Western cultures-
results in an inadequately developed immune system, making us all so much
more susceptible to infection. This was also reported in a popular science
magazine (Nature or similar) and was I think called "Let them eat dirt". Due
to my abysmal retrieval system for papers I cant find either, however I cant
remember him discussing at what stage this should apply, presumably not
children who are at an age where their immune system is immature.
