NCT04590521

Brief Summary

This is a single arm immunological study based in Vietnam. The study will examine human papillomavirus (HPV) vaccine responses in high-risk women (female-sex-worker; FSW). We aim to recruit 60 women (aged 18-25 years old) and provide them with a standard 3-dose schedule of licensed 4vHPV vaccine (Gardasil®, Merck). Blood and cervical swab samples will be collected for immunology and virology testing, respectively.

Study Arms (1)

Intervention

EXPERIMENTAL

A standard 3-dose schedule (0, 2 and 6 months) of licensed HPV vaccine (Gardasil®, Merck) will be administered to all participants intramuscularly.

Biological: Gardasil®, Merck

Interventions

Gardasil® (4vHPV) is a recombinant protein particulate (VLP) vaccine. Each 0.5 mL monodose pre-filled syringe or vial contains approximately 20 μg of HPV 6 L1 protein, 40 μg of HPV 11 L1 protein, 40 μg of HPV 16 L1 protein, and 20 μg of HPV 18 L1 protein as well as approximately 225 mcg of aluminum (as Amorphous Aluminum Hydroxyphosphate Sulfate adjuvant). It has completed phase III trials and is licensed for use in over 100 countries around the world including the United States, Australia and countries in the European Union (EU) for girls aged 9-26 years. Vietnam currently offer this vaccine in private health clinics, as a 3-dose schedule (0, 2 and 6 months).
