Got my initial hep b vaccine shot, three days before my hep-b std test. it came back positive for hep-b could my vaccine have skew my results?

It depends...: ...on the details of the positive blood test. Hepatitis B testing includes tests for hepatitis B surface antigen (HBsAg), antibody to surface antigen (HBsAb), and antibody to core antigen (HBcAb). If the only positive result on your blood test was HBsAg, then yes-- it might be the vaccine itself was detected. Of if the other(s), you may be immune and don't need vaccination. Discuss w/ the doctor.
