Does this violate Hipaa laws?

I'm going to India on very short notice, and I need to get going on all the shots. I need a history of all my immunizations, but cannot remember my childhood doctor (my mom died when I was 8 so this is why the name got lost in my family. That's a long story short).

Anyway, I called my high school and found out they do have my medical records of all my immunizations. But in order to get them, they are making me pay a $20 processing fee.

I don't have time to argue with them, and I don't want to sound like an absolute snob about paying them the fee, but it was brought to my attention that requiring a fee for medical history such as this probably violates Hippa laws.

I was just wondering if this is true or not. Please only serious answers from people who know what they are talking about, or have valid references. Thank you!
