Safety, Reactogenicity and Immunogenicity of Adenovirus Serotype 26 (Ad26)- and Modified Vaccinia Ankara (MVA)-Vectored Vaccine Components in Otherwise Healthy Women With HPV16 or HPV18 Infection of the Cervix

The main purpose of this study is to assess safety and reactogenicity of the 3 vaccine regimens.

This study is part of a vaccine program which aims to generate a therapeutic vaccine for women with HPV types 16 or 18 infection, with a focus on early disease interception. The study consists of 3 periods: Screening period of up to 42 days (6 weeks), followed by prime and boost immunizations and follow-up visits up to 12 months after the first vaccination. Evaluation of the safety/reactogenicity of the vaccine regimens will include physical assessment by study-site personnel, participant reports on signs and symptoms and laboratory assessments following vaccinations. Immunogenicity and Virology/Histology assessments will also be performed.
