I missed the cut-off for getting the HPV vaccs through school (I'm 24 and also in Scotland). I ended up getting the vaccinations anyway as my mum insisted - not sure if we had to pay! I've still had my screening as anyone else my age would have done starting at 20. Just as well as I have just had my treatment for CIN3 despite the vaccs (although due to my age when I got the jabs I probably picked up the HPV infection before then? The timeline of it is a bit fuzzy) Might be worth checking the NHS website?
