what is the difference between pneumonia prevnar for children or adults?

Does anyone know the difference between the "pneumonia vaccine" for adults vs. that for children?

I understand for babies/children it is called prevnar (Pneumococcal 7-valent Conjugate Vaccine, in the past, or prevnar 13 today I think, because it contains a few more strains) ... what is it in adults - the one for example talked about in this article recommended for those older than age 65 - if its something different than "prevnar" does it actually contain different strains, or are they actually the same ones included in prevnar, only they call it something different for old folks?

There are two types of pneumococcal vaccine, pneumococcal polysaccharide vaccine and pneumococcal conjugate vaccine.

The first pneumococcal polysaccharide vaccine was licensed in the United States in 1977. In 1983, an improved pneumococcal polysaccharide vaccine was licensed, containing purified protein from 23 types of pneumococcal bacteria (the old formulation contained 14 types). This pneumococcal polysaccharide vaccine is commonly known as PPSV23. The PPSV23 vaccine is licensed for use in adults and persons with certain risk factors who are age two years and older.

The pneumococcal conjugate vaccine was licensed in early 2000. It is recommended for use in preventing pneumococcal disease in infants and young children (from age six weeks to the 5th birthday). It is commonly known as PCV7.
