It's common in Poland to vaccinate newborns for common diseases like smallpox and I remember getting regular shots every now and then in school if some new disease poped up.

Difference was my parents had the option to opt out for whatever reason and they weren't threatened by the society for doing so.

If you receive threats and scorn for having the audacity to doubt and saying the word no then it should not suprise anyone if your apprehension grows.
