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.

Asthmatics between the ages of 19 and 80, without a history of recurrent bacterial infections. 5. individuals between the age of 19 and 80 who have a history of frequent bacterial infections and are being evaluated for humoral immunodeficiency.

Exclusion criteria

The following groups will be excluded: 1. Subjects who are currently receiving or have ever received immunoglobulin replacement therapy. 2. subjects who are on immune suppressive agents. 3. Subjects who are on chronic steroids or have received an intramuscular injection of steroids in the three months prior to enrollment or oral/intravenous steroids within a month of enrollment or two or more prednisone bursts in the past year. 4. subjects on antiepileptic agents. 5.
