The article does admit that in these boys it can be early stages of the avian flu that have not been manifested. However, if it is indeed what it
seems - a dorment virus due to individualized immunity this could be a godsend. I am having deja vu of the origin of the smallpox vaccine - from milk
maids exposed to a similar strain of pox over long periods of time.
Without a doubt, this will certainly be studied by industry as a way to make millions off of the unique case these boys present.
