NCT04274153

Brief Summary

The human papillomavirus (HPV) is the most common sexually transmitted infection (STI) in the United States (U.S.) and is responsible for a wide range of conditions, including cancers within the anogenital tract and the oropharynx. In just the U.S. alone, it's estimated that HPV causes 330,000 cases of precancerous cervical dysplasia and 12,000 cases of cervical cancer. The investigators propose a 2-dose HPV vaccination study in women seeking postpartum care at Johns Hopkins University. The investigators will measure the immunogenicity and acceptability of the vaccine in the postpartum setting.

Outcome Measures

Primary Outcomes (1)

  • Immunogenicity of a Two-dose 9-valent HPV Vaccination as Assessed by Antibody Titer

    Measure the immunogenicity of a two-dose 9-valent HPV vaccination regimen in postpartum women previously unvaccinated against the HPV 16 virus. Immunogenicity will be assessed by the antibody responses. The Geometric mean titers will be measured using milli Merck units (mMU)/mL.

    Up to 23 months

Secondary Outcomes (5)

  • Antibody Response to the Other 8 HPV Types

    Up to 23 months

  • Seropositivity for HPV 16 After 1-dose

    After the first dose, up to 7 months

  • Seropositivity for HPV 16 After 2-doses

    After the second dose, up to 2 months

  • Percentage of Participants With Baseline Titers Suggestive of Natural Inoculation or Prior Vaccination to HPV 16

    Baseline

  • Percentage of Participants Who Complete 2-dose Vaccination

    At the end of the study, up to 2 years

Study Arms (1)

Gardasil9

EXPERIMENTAL

Two doses of the 9-valent HPV vaccine to be administered to participants at 0 and 6 months. Additional HPV vaccine dose will be offered after final blood draw at 12 months.

Biological: Gardasil9

Interventions

Gardasil9BIOLOGICAL

Two doses of the HPV vaccine across a 12 month period (two doses of 0.5mL).

Gardasil9
