Totally understand, I thought the same too! Thing is, there are just to many good reasons for it. Someone has to be first and really, our girls aren't first anyway, they are second - its been trialed enough!
If it makes you feel any better, my DD's school was the first in the country to have it done! Top tip. She will have a stiff arm for a couple of days after, and the stiff arrives quiet quickly after the jab. If you can, either give her a couple of Ibruprofen before she goes to school that day or shove a couple in her bag for when she needs then.
