>At the risk of seeming provocative: many of us vaccinate our children against various undesirable consequences. Many of us have started or are about to start vaccinating teenage girls against a particular virus that is strongly associated with cervical cancer and which seems to be sexually transmitted. I believe that pregnancy is sexually transmitted too. Join the dots. ;-)

Did... and didn't get the "start". I thought the vaccine is an one-time thing, not something you start and then have to keep doing.

And mind you, we have three daughters. We are aware they are human.
