Basically, you pay tons of money (this would be the most expensive thing in the game) to give one of your Pokemon the "Pokerus cured" status. With this, you get the EV boost, but it can't be spread. It would be just like if you let Pokerus cure naturally, but it's put on your Pokemon that way. Pokerus itself would still exist, but it would be free (very much unlike this vaccine) and it would spread like usual.
What do you guys think?
I'm not easily impressed; I'm usually oblivious to whatever's in front of me.
Not exactly. With the whole Wi-Fi trading thing, it's pretty darn easy to get Pokerus. Granted, not everyone does that, and not everyone has access, but I'd imagine most people do, and for them, it's not an issue.
