Oh gosh, I've been umming and ahhing over this too.

10years ago when they were developing the first one (I worked as the Kids Hospital) and lots of the nurses there were not wanting their kids to have the new vax as the side effects were so unknown. Same with the chicken pox vax when it was developed.
I wish they could routinely swab all the kids as many have natural immunity, but they can't....shame I got this the day after DS was at the GP too, or I would have talked to her about it.
After all the issues with guardasil I'm still not sure. Going to talk to the middies next week at my check.
