I'm assuming you are referring to the Pneumovax 23? This is the pneumonia vaccine that is recommended as routine for those age 50+ or persons age 2 or older with certain chronic conditions or in certain environmental or social situations...
Usually only one dose of this vaccine is needed, except under certain cicumstances such as:
A second dose is recommended for people 65 years and older who got their first dose when they were younger than 65 and it has been 5 or more years since the first dose.
A second dose is recommended for people 2 through 64 years of age who: - have a damaged spleen or no spleen - have sickle-cell disease - have HIV infection or AIDS - have cancer, leukemia, lymphoma, multiple myeloma - have nephrotic syndrome - have had an organ or bone marrow transplant - are taking medication that lowers immunity (such as chemotherapy or long-term steroids).
When a second dose is given, it should be given 5 years after the first dose.
Here is a Vaccine Information Statement with more information: http://www.cdc.gov/vaccines/pubs/vis/downloads/vis-ppv.pdf
