A Trial to Establish Non-inferiority of Immunogenicity of a Single-dose of CERVAVAC® Quadrivalent HPV Vaccine Compared to the Gardasil® Quadrivalent Vaccine Among Girls and Boys Aged 9 to 14 Years and in Girls/Women Aged 15 to 20 Years in Zambia

A Randomized, Active Controlled, Assessors-blind Trial to Establish Non-inferiority of Immunogenicity of a Single-dose of CERVAVAC® Quadrivalent HPV Vaccine Compared to the Gardasil® Quadrivalent Vaccine Among Girls and Boys Aged 9 to 14 Years and in Girls/Women Aged 15 to 20 Years in Zambia

Brief summary (registry, in English)

The goal of this study is to compare the immune response of the single dose of the CERVAVAC vaccine with the single dose of Gardasil vaccine in girls/women aged 9 to 20 and boys aged 9 to 14 at 6 months, 12 months and 24 months post vaccination. The vaccine will be given randomly to the boys and girls/women in these age group and they will be followed up to check the immune status developed in them after vaccination. The status of immune response developed by the two differnet vaccines will be compared in these group of participants of the study.

  • Participant with a current diagnosis or prior history of cervical intraepithelial neoplasia (CIN) or cervical cancer.
  • Participant has had an acute illness (moderate or severe) and/or fever (body temperature ≥ 38°C or ≥ 100.4 °F) at the time of vaccination or during the 72 hours prior to the vaccination.
  • Participant has had chronic administration (defined as more than 14 days) of high doses of corticosteroids (prednisone or equivalent at a dose of \>0.5 mg/kg/day), cytotoxic agents or radiotherapy or immunoglobulins, immunosuppressants or other immune-modifying drugs in last 3 months or planned at any time during the study.
  • Participant has history of receiving a blood transfusion or other blood products in three months prior to screening.
