pneumococcal polyvalent vaccine
An polyvalent vaccine used to prevent infection by the bacterium Streptococcus pneumoniae. Pneumococcal polyvalent vaccine contains higly purified capsular antigens from the 23 most prevalent or invasive pneumococcal types of Streptococcus pneumoniae to ensure cross-protection. Following vaccination, protective capsular type-specific
antibody levels typically develop by the third week; serotype-specific antibody levels generally decline after 5-10 years. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)
