Meningococcal Disease, Invasive Clinical Trial
Official title:
A Randomized, Controlled Trial to Compare Protection in Adolescents Between Different Meningococcal Immunization Schedules Used in Canada; a Canadian Immunization Research Network (CIRN) Study.
This study is to confirm non-inferiority of the three MenACWY vaccines (Menveo, Menactra or Nimenrix) in adolescents, and to identify whether the number of previous doses of MenC influences the response to the MenACWY vaccine.
Participants will be randomized to receive one of the three doses of licensed MenACWY as a booster dose in adolescents. Serology will be collect at 3 time points; prior to the booster dose and 1 month and 1 year post-vaccination to measure antibody levels. The participants are healthy students in grades 7-9 who have not received their MenACWY vaccine yet and received their routine infant MenC vaccines per previous Canadian schedules. ;
