Brief Title  ICMJE Persistence of Antibodies After Meningococcal Vaccine PF-06866681 in Healthy Children
Official Title  ICMJE A PHASE III, OPEN, MULTI-CENTRE, CONTROLLED STUDY TO EVALUATE THE LONG-TERM ANTIBODY PERSISTENCE AT 2, 3, 4, 5 AND 6 YEARS AFTER A BOOSTER DOSE OF MENINGOCOCCAL SEROGROUP A, C, W-135, Y- TETANUS TOXOID CONJUGATE VACCINE (MENACWY-TT) OR MENINGITEC (REGISTERED) ADMINISTERED IN HEALTHY 5-YEAR-OLD CHILDREN IN STUDY MENACWY-TT-048 EXT: 039 Y2, 3, 4, 5 (112036), WHO WERE PRIMED WITH THE SAME VACCINE IN STUDY MENACWY-TT-039 (109670) AT 12 THROUGH 23 MONTHS OF AGE.
