- Positive tests for Hepatitis B and/or C infection An abnormal value will be defined by the ranges quoted by The Doctors Laboratory for the Vaccine Institute site and Pathology Department, York Hospital for the York site.
- They have a known or suspected impairment of lung, heart, liver, kidney, diseases, blood disorders or immune dysfunction.
- They are receiving immunosuppressive therapy (including systemic steroids).
