Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Group 1
Group 1: girls who received 2 doses of Q-HPV vaccine at 0, 6 month schedule 8-10 years ago when they were between 9-13 years of age at the time of the first dose. The intervention of a single dose of licensed Gardasil 9 vaccine (Human Papillomavirus 9-valent Vaccine, Recombinant) will be administered at Day 0 of the study.
Human Papillomavirus 9-valent Vaccine, Recombinant
All groups will receive a single dose of the Gardasil9 vaccine at Visit 1/Day 0 of the study.
Group 2
Group 2: girls who received 3 doses of Q-HPV vaccine at 0, 2, 6 month schedule 8-10 years ago when they were between 9-13 years of age at the time of the first dose. The intervention of a single dose of licensed Gardasil 9 vaccine (Human Papillomavirus 9-valent Vaccine, Recombinant) will be administered at Day 0 of the study.
Human Papillomavirus 9-valent Vaccine, Recombinant
All groups will receive a single dose of the Gardasil9 vaccine at Visit 1/Day 0 of the study.
Group 3
Group 3: young women who received 3 doses of Q-HPV vaccine at 0, 2, 6 month schedule 8-10 years ago when they were between 16-26 years of age at the time of the first dose. The intervention of a single dose of licensed Gardasil 9 vaccine (Human Papillomavirus 9-valent Vaccine, Recombinant) will be administered at Day 0 of the study.
Human Papillomavirus 9-valent Vaccine, Recombinant
All groups will receive a single dose of the Gardasil9 vaccine at Visit 1/Day 0 of the study.
