Where's the link?

There is some opposition to this plan to vaccinate all 12-13 year old girls against the virus which is likely to cause cervical cancer on the grounds that it will encourage promiscuity. I can't see the connection. A potentially promiscuous young girl is not going to become more or less so because she has had, or has not had, a vaccination. Equally a "good" girl is not going to become more or less good as a result. The root causes of promiscuity are many and varied, but I don't think having an injection ranks amongst them.
