If I had to guess, I would say that it's just a slapped-together crappy vaccine that isn't very effective and can cause bad reactions in some people. The real purpose is to make money and trick people into thinking they're much more dependent on frequent "health care" than they really are. People who think they'll die without constant vaccines and medications are much easier to control than people who know they'll probably be fine on their own.

It might be something nastier. Even if it's not, the control scam explanation is bad enough and I don't want it.
