Cancer vaccine from cat poop?

[Catherine]

Quote:I suspect that someone discovered that the Toxoplasmosis parasite could be used in this way and then looked for a source of it. There are probably other variants that would have the same effect but the cat version is readily available, relatively.

There is no shortage of cat poop.
I also think the parasite is fairly common. It would be a very unlikely source for a cure, but wouldn't it be incredible if it worked.
