I got my hep b series for free through a hospice where I volunteered. 🙂 If you're volunteering, see if that's an option. The health dept. or your school clinic is generally your best bet because insurance really night not cover all the stuff -- I know you young guys think insurance covers everything your doctor submits, but it's so not true. If your insurance company doesn't deem the shots to be medically necessary (and they night not be), you're stuck with the bill.
