Exclusion Criteria

1. Any confirmed or suspected current immunosuppressive or immunodeficient condition since the end of V37\_07E1 study, based on medical history and physical examination (no laboratory testing required).
2. Treatment with corticosteroids or other immunosuppressive/immunostimulant drugs as defined below:

i) chronic use of oral and parenteral immunosuppressants (\>= 15 days of use) or other immune-modifying drugs within 60 days prior to the blood sampling (short term usage of topical, inhaled and/or intranasal corticosteroids were allowed) ii) receipt of immunostimulants within 60 days prior to Visit 1
3. Administration of immunoglobulins and/or any blood products up to 3 months before enrollment.
4. Use of any investigational or non-registered product (drug or vaccine) within 30 days preceding the blood sampling.
