Before DYK, MAYER, and REYNA, Circuit Judges. DYK, Circuit Judge. Curtis Scott appeals from the decision of the United States Court of Appeals for Veterans Claims (“Veterans Court”) denying his claim for service connection for hepatitis C.  We affirm.
Scott served on active duty for training in the United States Marine Corps Reserve from January to July 1972.  On November 18, 1999, Scott tested positive for hepatitis C.  He applied for disability benefits on February 4, 2005, alleging that he contracted hepatitis C in service.  His primary theory was that he was infected with hepatitis C when he received air-gun inoculations during his military service.  The Department of Veterans Affairs (“VA”) regional office (“RO”) denied Scott’s claim for service connection on September 20, 2005.
