Pneumococcal conjugate vaccine (PCV) is a pneumococcal vaccine used to protect infants and young children against disease caused by the bacteria Streptococcus pneumoniae (pneumococcus). There are currently three PCV vaccines available on the global market: Prevnar (called Prevenar in some countries) Synflorix and Prevnar 13. Prevnar is a heptavalent vaccine meaning that it contains the cell membrane sugars of seven serotypes of pneumococcus conjugated with Diphtheria proteins.
