Patogener har kopierat spermiers "Carte Blanche" kolhydratskod
Det kan finnas en orsak till att det är svårt att vaccinera mot vissa virus (HIV), vissa cancerformer och vissa bakterier (Helicobacter Pylori). Bakterier, virus och vissa typer av cancer har lyckats duplicera den kolhydratsekvens som spermier använder för att stänga av värdens immunförsvar.

“It’s our major Achilles heel,” Clark said. “Reproduction is required for the survival of our species. Therefore we are ‘hard-wired’ to protect our sperm and eggs as well as our unborn babies from any type of immune response. Unfortunately, our results suggest that many pathogens and tumor cells also have integrated themselves into this protective system, thus enabling them to resist the human immune response.”
