Persistence of Antibodies After Meningococcal Vaccine PF-06866681 in Healthy Children

March 13, 2019 updated by: Pfizer

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.

The purpose of this study is to evaluate the long-term antibody persistence as well as safety of GSK Biologicals' MenACWY-TT vaccine versus Meningitec up to 6 years after booster vaccination administered in healthy 5 year old children in the study MENACWY-TT-048 EXT: 039 Y2, 3, 4, 5 (NCT00955682), who were primed with the same vaccine in the study MENACWY-TT-039 (NCT00474266) at 12 through 23 months of age.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers
