The video proports to be a pentagon briefing from 2005 about a proposal to spread a virus in the Middle East that would prevent people from developing extreme religious views. Besides the obviously ludicrous nature of this idea, the video itself is fake, a deliberate hoax. The most telling thing is that the graphic that supposed shows "two different individuals" is actually two images of the same brain.
More telling, it's actually the brain of a 43 year old meth addict, taken from this article in the Dec 2010 issue of Neurology.
So, a video uploaded in 2011 is supposedly a secret Pentagon video from 2005. But actually used photoshopped images from an unrelated 2010 article. Since the image did not exist until 2010, this proves the video is a fake.
So who is behind it? The most likely candidate is Ryan Harper, who ran a failed Kickstarter project to make a documentary about it:
So I think it's very likely that Ryan Harper made the original FunVax hoax film himself. He's well suited to the task, working in biotech, and also making films.
Ryan Harper registered funvax.com on 2011-04-03 (April 3rd, 2011), two months before the "Joey Lambardi" video was released.
Note: I found the older brain scan image with Google Images:
