Immunogenicity and Safety of HPV-4 Vaccine With or Without Td Vaccine in Children

September 11, 2026 updated by: PT Bio Farma

Evaluation of Safety and Immunogenicity of Co-administering Human Papillomavirus (HPV) Vaccine With Td Vaccines in Healthy Population Aged 9-15 Years Old in Indonesia

This study will evaluate the safety and immune response of a single dose of a quadrivalent human papillomavirus (HPV) vaccine when given together with a tetanus-diphtheria (Td) vaccine in healthy children and adolescents aged 9 to 15 years. The study will compare participants who receive the HPV vaccine together with the Td vaccine with those who receive the HPV vaccine alone. The study will assess whether giving the two vaccines together produces an immune response to HPV that is not lower than giving the HPV vaccine alone.

Study Overview

Detailed Description

This study is a randomized, open-label, two-arm, parallel-group, prospective interventional Phase III trial designed to evaluate the immunogenicity and safety of a quadrivalent human papillomavirus (HPV) vaccine when administered concomitantly with a tetanus-diphtheria (Td) vaccine in healthy children and adolescents aged 9 to 15 years.

Participants will be assigned to receive the quadrivalent HPV vaccine together with the Td vaccine or the quadrivalent HPV vaccine alone. The study will assess antibody responses to the HPV vaccine antigens. Safety will be evaluated throughout the study by monitoring solicited and unsolicited adverse events, serious adverse events, and other clinically relevant safety findings.

The study is intended to provide clinical evidence on the concomitant administration of the quadrivalent HPV vaccine with Td vaccine in the target pediatric population.

A single 0.5 mL dose of Adsorbed Td (Tetanus-Diphtheria Toxoid) Vaccine Bio Farma containing purified tetanus toxoid and purified diphtheria toxoid.
Other Names:
  • Bio Td
  • Td Vaccines
Active Comparator: 4vHPV alone
Participants receive a single dose of quadrivalent HPV vaccine alone.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Number and percentage of subjects seroconverted for anti-HPV types 6, 11, 16, and 18
Time Frame: 28 days after vaccination
Number and percentage of subjects who seroconvert for anti-HPV types 6, 11, 16, and 18. Seroconversion is defined as the appearance of antibodies with titers greater than or equal to the predefined lower limit of quantification (LLOQ) in the serum of subjects who are seronegative before vaccination, as measured by enzyme-linked immunosorbent assay (ELISA). The seroconversion rate in the group receiving 4vHPV vaccine co-administered with Td vaccine will be compared with that in the group receiving 4vHPV vaccine alone to evaluate non-inferiority.
28 days after vaccination
