Study Evaluating Serum Collected From Healthy Adults For Development of Pneumococcal Opsonophagocytic Assay

Blood Collection In Healthy Adult Volunteers To Obtain Serum For Use In Pneumococcal Opsonophagocytic Assay Development.

The study will identify healthy adults who have been vaccinated against pneumococcus, and collect blood for the purpose of developing laboratory assays.

Collect serum with antibody levels capable of killing pneumococcal bacteria from healthy prevaccinated adults to develop OPA assays for the 13 serotypes in 13-valent pneumococcal conjugate vaccine.

Inclusion Criteria:

• Healthy adults 18-70 years of age
• Must have received 23vPS pneumococcal vaccine

Exclusion Criteria:

• Bleeding diathesis
• Pregnancy
• Chronic disease which could be worsened by donating blood
