Both: PCV 13 or Prevnar (pneumococcal vaccine) is more effective as the newer generation of vaccines which used a different molecule for better antibody response. The old polysaccharide vaccine PPSV 23 covers more strains of the pneumococcus bacteria and is still recommended for a back up.

Both are recommended: There is overlap between the vaccines, but some individuals get a better response from the PCV13 vaccine. See the article published in Morbidity and Mortality:http://www.cdc.gov/mmwr/preview/mmwrhtml/mm6337a4.htm
