I have never seen those dolls in real life, but I did know the sad story behind them.
In my country vaccinations are mandatory by law. Parents that do not oblige face financial penalties that keep repeating and increasing for as long as they do not give in and consent to poisoning their children. The authorities are in the process of making that legislation even stricter (as if that was possible). That's the current situation in my part of the woods. And that's why I don't live there any more.
