Like you said if you're seen as bein "careless" or in a high risk profession that would expose you to HIV, Hep etc banks are less likely to give you money incase you catch something and die before you can pay them back.

 

Techinically the fact that you have the vaccinations or have gone for the tests can't be used against you, but the fact that it's on your medical record if you go through your doctor means that banks will see that if you're applying for a mortgage. No explination of the tests will been shown so the banks can draw their own conclusions.

 

If you're in the UK there's the British School of Body Piercing website/email can direct you to the more reputable courses.

 

If you're in the USA Fakir Musafar (not him but people he has trained) runs a piercing course in  California.

I'd looked into the Fakir course before i started working in the studio, but it was gonna be well expensive to fly over to the USA and pay for the course.
