Additional Dose Qualifiers

Studies showed inadequate immune responses to only two doses in people with the following conditions:

• Active cancer treatment for tumors or cancers of the blood
• Organ transplant recipients who are taking medicine to suppress the immune system
• Stem cell transplant recipients (within the last 2 years or taking immunosuppressive medications)
• Moderate or severe primary immunodeficiency (such as DiGeorge syndrome, Wiskott-Aldrich syndrome)
• Advanced or untreated HIV infection
• Active treatment with high-dose corticosteroids (e.g. cortisone, prednisone) or other drugs that may suppress your immune response.

  If you have a question about whether you should receive an additional dose, please contact your health care provider.

  NOTE:  If you have not completed your two-dose series, your additional dose can be scheduled at the completion of your second vaccination.
