New 9-Valent HPV vaccine aims to block more Cancer-Causing viruses
NCT ID NCT04537156
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This Phase 3 trial tests a 9-valent HPV vaccine in over 9,000 healthy women aged 18-45. The vaccine targets nine HPV types linked to cervical cancer and genital warts. Researchers compare it to an existing 2-valent vaccine to see if it provides broader protection. The goal is to prevent persistent infections, precancerous lesions, and related diseases.
