• Adverse reactions to vaccines such as anaphylaxis or other serious reactions, e.g. life-threatening reactions to medicine
• History of immunodeficiency or autoimmune disease such as rheumatoid arthritis, systemic lupus erythematosus, scleroderma, polymyositis dermatomyositis, juvenile onset insulin dependent diabetes, or a vasculitic syndrome
