The high-risk group gets vaccinated @ time of diagnosis and ONE time re-vaccination in 5 years. "Normal" people get vaccinated at age 65, with no re-vaccination. This is all the info you'll need for board purposes.
I believe the exam questions are based on the recommendations from the US Preventive Task Force? The task force website defers to the CDC on immunizations,

Which states:
6. Pneumococcal polysaccharide vaccination
Medical indications: chronic pulmonary disease (excluding asthma); chronic cardiovascular diseases; diabetes mellitus; chronic liver diseases, including liver disease as a result of alcohol abuse (e.g., cirrhosis); chronic alcoholism, chronic renal failure, or nephrotic syndrome; functional or anatomic asplenia (e.g., sickle cell disease or splenectomy [if elective splenectomy is planned, vaccinate at least 2 weeks before surgery]); immunosuppressive conditions; and cochlear implants and cerebrospinal fluid leaks. Vaccinate as close to HIV diagnosis as possible.
Other indications: Alaska Natives and certain American Indian populations and residents of nursing homes or other long-term--care facilities.
7. Revaccination with pneumococcal polysaccharide vaccine
One-time revaccination after 5 years for persons with chronic renal failure or nephrotic syndrome; functional or anatomic asplenia (e.g., sickle cell disease or splenectomy); or immunosuppressive conditions. For persons aged >65 years, one-time revaccination if they were vaccinated >5 years previously and were aged <65 years at the time of primary vaccination.
