Pneumococcal Post-Vaccination Titers
Study Details
Study Description
Brief Summary
The study is looking at the pneumonia vaccine and the immune system response to this vaccine. The information gathered from this study may be important for your doctor to take care of patients with smoking histories, immune deficiency, asthma, Chronic Obstructive Pulmonary Disease (COPD), or elderly patients. It is important that your immune system builds a strong defense to the vaccine so that you are better able to fight a bacterium that can cause pneumonia. Some disease prevent the immune system from building a strong defense and these patients will not benefit from the vaccine.

Detailed Description
One hundred forty subjects will have pre-vaccination titers checked for the 23 serotypes in the PPV-23 vaccine. They will then receive the vaccine. All subjects will be given the vaccination as standard of care. Approximately 4 weeks following immunization, the subjects will have post-vaccination titers checked to the same serotypes checked prior to vaccination.
