Where Can A Student Get Immunization Shots in Dallas?

I was recently accepted into TWU's nursing program and need to get my immunization records in order. I know I can pull up my previous records from my high school records. But what I really need to know is where can I go that accepts my insurance, United Healthcare, to get the Hep B and DPT vaccines in the Dallas area?

I checked with my primary physician and his office doesn't offer it. Someone recommended the Dallas County Health Department, but they charge too much in my opinion and don't accept insurance. Does anyone know of a clinic in the Dallas metroplex that does the immunication shots for nursing students AND accept insurance?
