Immunogenicity of 2 vs. 3 doses of HPV vaccination in immunocompetent girls

Population : Immunocompetent females
Intervention: 2 doses of HPV vaccination in girls (9-14 years)
Comparison: 3 doses of HPV vaccination in girls or women
Outcome : Immunogenicity (GMT)
What is the scientific evidence of non-inferior immunogenicity of a 2 dose HPV vaccination schedule in girls (9-14 years) compared to a three dose schedule in girls or women?
