What was measured

Serum antibody titers for HPV virus-like particles (VLPs), Types 6, 11, 16, 18, 31, 33, 45, 52 and 58 were determined 4 weeks post-vaccination 3 using competitive luminex immunoassay (cLIA). The serostatus cutoffs (milli Merck U/mL) for HPV types were as follows: HPV Type 6: ≥30, HPV Type 11: ≥16; HPV Type 16: ≥20, HPV Type 18: ≥24, HPV Type 31: ≥10, HPV Type 33: ≥8, HPV Type 45: ≥8, HPV Type 52: ≥8, and HPV Type 58: ≥8.

Analysis population: Participants who received all 3 vaccinations within an acceptable day range, had Month 7 serology sample collected within an acceptable range and had no other protocol violations that could interfere with immunes response to the vaccine. Statistical testing performed only within the 9vHPV arm and only for HPV types 31, 33, 45, 52, and 58.

Groups in this outcome

9vHPV Vaccine - Base Study

Blinded 9vHPV vaccine (V503) 0.5 mL intramuscular injection at Day 1, Month 2, and Month 6 of the Base Study. Participants will not continue to the Extension Study.

Placebo - Base Study

Blinded 0.5 mL intramuscular injection of saline placebo at Day 1, Month 2, and Month 6 of the Base Study. After completion of the Base Study, participants will be eligible to receive open-label 9vHPV 0.5 mL intramuscular injection at Day 1, Month 2, and Month 6 of the Extension Study.

Group identifiers and denominators belong to this outcome only. They may differ in another outcome or in safety reporting.
