A vaccine against cocaine

This is different. A vaccine has been developed which offers long-lasting immunity against a cocaine high, the idea being that the man or woman on Hastings street (for example) who wants out need only take this vaccination, probably with a couple boosters.

“The vaccine eats up the cocaine in the blood like a little Pac-man before it can reach the brain,” the study’s lead investigator, Dr. Ronald G. Crystal, said in a news release. “We believe this strategy is a win-win for those individuals, among the estimated 1.4 million cocaine users in the United States, who are committed to breaking their addiction to the drug. Even if a person who receives the anti-cocaine vaccine falls off the wagon, cocaine will have no effect.”

You know, I'm kind of tired of the Pac-man analogy. I think that you can pretty much tell it like it is when it comes to antibodies and how they work - people will understand. I'm sure Dr. Crystal has good intentions, but "like a little Pac-man"? Come on. It's one thing to make technical stuff digestible for the public, it's another thing to underestimate just what the public is capable of understanding.
