Interesting..................it was in clinical trials in 2001.....time to get this baby to market.
That is definitely an interesting article. If I might venture a guess based on the dates and the respective information in the articles, this seems to have been first developed solely (or at least primarily) with the intent of treating HIV. What might've happened is that when it was discovered that HIV mostly hides out in the lymphs they realized this wouldn't work for that. However, they switched gears and have been developing it for other blood-borne diseases, especially bioweapon threats.
That's just conjecture on my part, but that would strike me as explaining the five year timespan and the different focus between the 2001 article and this 2006 article.
