Charlie Sheen thinks vaccinations are poison. So do a lot of other celebrities, including Jenny McCarthy and  her boyfriend, Jim Carrey.

But his ex-wife Denise Richards apparently thinks that both reality TV shows and vaccinations are safe for kids. So naturally, there’s a big battle brewing.

TMZ reports that Sheen’s sent a legal letter to the girls’ physician stating his lack of consent for the doctor to treat his daughters.
