Pneumococcal Post-Vaccination Titers

Status unconfirmed · Not applicable

Conditions studied: Smokers, Elderly, Asthma, COPD, Recurrent Infections

In brief

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.
