I got my Hep B at the Wellness Center in Covington. At first they said no b/c I was over 18 but then the office said that it was ok and gave it to me. It was only $10 per shot and they were really nice. The State supplies them with only a certain amount of each vaccine, but they mostly deal with WIC, food stamps, basic mother/child healthcare so I don't think their demand for Hep B is very big. Call them first b/c it has been a while since I received them. 985-871-6030. Their address is 1505 N. Florida St. Covington, LA 70433. Good luck!
