HPV Immunization in Ghana to See if Vaccine Works in Babies and Teens
Official title: A Randomized, Observer-Blind, Placebo-Controlled, Proof-of-Concept Study to Assess the Safety, Tolerability and Immunogenicity of a Bivalent Human Papillomavirus (HPV) Vaccine in 9 and 15 Month Old Infants and Toddlers, 2-5 Year Old Children and an Open Label Single Dose Study in Young Unmarried Females Aged 15-20 Years in Ghana
Run by International Vaccine Institute · NCT07377656 · Data updated 2026-11-12
This study tests whether a bivalent HPV vaccine is safe and can provoke an immune response in healthy infants and young children, and compares it to responses seen in unmarried young women aged 15–20 in Ghana.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are healthy infants and toddlers aged 9 to 15 months or 2 to 5 years, and unmarried females aged 15 to 20 years, living in or near Dodowa, Ghana, who are HIV-negative and, for older females, not pregnant and willing to use contraception.
✕Probably not a fit
Patients unlikely to benefit include those with contraindications to vaccines, pregnant individuals, and those not planning to stay in the study area for its duration.

What this trial studies
This is a phase 2 randomized, observer-blind, placebo-controlled proof-of-concept study conducted in Ghana. It evaluates the safety, tolerability, and immunogenicity of the bivalent Cecolin HPV vaccine given to 9- and 15-month-olds, and 2- to 5-year-olds, with a parallel open-label comparison in 15–20-year-old unmarried females. The trial includes an HPV vaccine arm, a placebo arm, and a measles-rubella vaccine arm as a control. Primary outcomes focus on short-term safety and antibody responses, with a goal of determining whether pediatric vaccination elicits immune responses comparable to those observed in older females where efficacy has been demonstrated. The study is conducted at the Dodowa Health Research Centre and involves collaboration among IVI, Karolinska Institutet, Noguchi Memorial Institute for Medical Research, and the Dodowa site.
Why it matters
Potential benefit: If successful, the findings could support expanding HPV vaccination to younger age groups and inform future strategies to reduce cervical cancer risk.
How similar studies have gone: Previous HPV vaccine studies in older age groups show strong immunogenicity and safety, but this pediatric age group and cross-age comparison is relatively novel and exploratory.

Inclusion Criteria: * Healthy male and female individuals aged 9 months, 15 months, 2-5 years and unmarried females aged 15-20 years at the time of vaccination * Participants aged 9 months, 15 months and 2-5 years who are up to date with their EPI vaccinations. * Residing within the area of the study and planning to stay for the study duration. * Participants that are HIV negative at screening (for the 9-15-month-olds a documented negative maternal ANC HIV screening). * Unmarried females with a negative pregnancy test at screening practicing/willing to practice continuous effective contraception as recommended by the Ghana Health Services guidance in Ghana * Able and willing to comply with all study requirements. * Willingness to provide written informed consent before any trial procedure. Assent will be required for young female participants aged 15-17 years at vaccination in addition to their parent's/LAR's consent. Exclusion Criteria: An individual who meets any of the following criteria will be excluded from participation in this study: * Pregnancy, lactation, or intention to become pregnant during the vaccination phase through three months after the study vaccine dose * Previous vaccination against HPV (Only for the 15-20-year-old efficacy cohort) * Presence of malnutrition (weight-for-length z-score ≤-2SD median, per WHO published child growth standards) * Planning to migrate out of the study areas before the end of the study follow-up * Any underlying known condition or criteria, including acute or chronic clinically significant abnormality or infection that in the opinion of the investigator might compromise the wellbeing of the participant or interfere with the outcome of the study. * Administration of immunoglobulins and/ or any blood products within the three months preceding the administration of the study vaccine. * Known history of allergy or anaphylaxis to study vaccine components and/or excipients or other medications, or any other allergies deemed by the investigator to increase the risk of an adverse reaction. * Any confirmed or suspected immunosuppressive or immunodeficient state, asplenia, recurrent severe infections and chronic use (more than 14 days) of immunosuppressant medication within 3 months prior to recruitment (topical steroids may be allowed). * Any other finding that in the opinion of the investigators would increase the risk of an adverse outcome from participation in the trial or result in incomplete or poor-quality data.
