Participant Flow

This was a Phase III study. The first patient was enrolled (FPE) on 13-Jul-2007. The last patient last visit (LPLV) was on 30-May-2008. A total of 5 US study centers were involved in the recruitment.

Base trial 4/97-4/98 Prior to results posted Initial: subjects received 1st or 2nd dose of PN23 Persistence: followed immune response 5 yrs; ended 4/03 Extension 7/07-4/08: enrolled 9-10 yrs after base. 1dose of PN23 Blood drawn Days 1\&30, immune response to 8 serotypes measured 143 of 400 enrolled: difficulty enrolling eligible/interested subjects
