I can see it now.
"No, my daughter at age 10 isn't haveing sex".
Doctor: "It's mandatory to have this shot."
If you are a good parent, you'll decide to give it by yourself to avoid this conversation at age 16:
Doctor: I am sorry, your daughter has cervical cancer
You: But I told her not to have sex...
No Problem ...
Just wait until your daughter comes up to you and announces that she is going to have sex - then get her to wait six months until the series of 3 shots can be completed.
Sure ... that'll work ...
