 - Use of any investigational or non-registered product (drug or vaccine) other than the study vaccines within 30 days preceding the booster dose of study vaccines, or planned use during the study period (active phase and 5 months extended safety follow-up).
 - Chronic administration of immunosuppressants or other immune-modifying drugs within 6 months prior to the booster dose of study vaccine.
