CPRIT FY 2024 Annual Report Published Research Findings

The HPV vaccination is the safest and most effective way to prevent six kinds of HPV-related cancers. The U.S. Advisory Committee on Immunization Practices currently recommends a two-dose series among individuals 9 to 14years of age and a three-dose series among individuals 15 to 26 years of age. Because data comparing two versus three doses of 9vHPV vaccine in individuals aged 15 to 26 years of age are limited, Abbey Berenson, M.D., Ph.D., professor, Departments of Obstetrics & Gynecology and Pediatrics, and director, Center for Interdisciplinary Research in Women’s Health at The University of Texas Medical Branch at Galveston, and colleagues set out to uncover the differences.
The preliminary findings of this ongoing, single-blinded, randomized trial of the 9vHPV vaccine among individuals 15 to 26 years of age in the United States were published in NEJM Evidence on January 23. The team enrolled and randomly assigned 438 participants to the two-dose (n=217) or three-dose (n=221) group. At one month after the final vaccine dose, the seroconversion rate for each of the nine HPV genotypes in the vaccine was 100% among participants in the two-dose group and 99% in the three-dose group. These results suggest that two doses of the 9vHPV vaccine may be sufficient to fully vaccinate adolescents and young adults.
“Because of the current discourse within the medical community about how many HPV vaccine doses are sufficient, it was important to publish the preliminary findings of our study sooner, rather than later,” Dr. Berenson said. “No study has previously examined the non-inferiority of the 9vHPV vaccine among 15- to 26-year-olds. Thus, our findings are beginning to fill an important gap of knowledge within the medical field.”
The University of Texas Medical Branch at Galveston received a $1.5 million CPRIT Academic Research grant (RP190022) in 2019 for a randomized, controlled trial comparing the immunogenicity of 2 doses vs. 3 doses of the 9-valent HPV vaccine in females and males 15 to 26 years of age.

CPRIT FY2024 Prevention Highlights

In October 2023, St. Jude Children’s Research Hospital published an online article, “Partnering with Schools to Increase HPV Vaccine Coverage in Rural Communities along the U.S.-Mexico Border,” lauding the CPRIT-funded school-based HPV vaccination program in the Lower Rio Grande Valley. According to the recently released NIS-Teen 2022 data, for the first time since the HPV vaccine became available, vaccination rates did not increase. Instead, rates of HPV vaccination initiation (i.e., ≥1 dose) and up-to-date coverage nationally remained steady from 2021 to 2022. Coverage declined among uninsured and Medicaid-insured teens and HPV vaccination rates remained significantly lower among teens living in rural areas. The Lower Rio Grande Valley in Texas is a medically underserved area, where approximately one in three residents are uninsured.
Through a series of grants from CPRIT, a team of researchers, including Jane Montealegre, Ph.D., associate professor, Department of Behavioral Science at The University of Texas MD Anderson Cancer Center, and Abbey Berenson, M.D., Ph.D., professor, Departments of Obstetrics & Gynecology and Pediatrics, and director, Center for Interdisciplinary Research in Women’s Health at The University of Texas Medical Branch at Galveston, along with public health practitioners is working to make HPV vaccination, and other routinely recommended and catch-up adolescent vaccinations, widely available at middle schools throughout the region. The team works with school district leadership and nurses to plan on-campus, school vaccination events that students can attend throughout the day at no cost to participants. Of equal importance is the education campaign around HPV vaccination targeting parents and caregivers, school faculty and staff, and local healthcare providers. In one school district, HPV vaccination initiation rates among middle-school students increased from 39.7% at baseline to 68.5% in Year 3 of the three-year program. Other school districts are experiencing similar results as the program continues to grow and expand its reach into more rural and remote counties along the U.S.-Mexico border.
Baylor College of Medicine received two Prevention grants (PP210007, PP220038) totaling $5 million and The University of Texas Medical Branch at Galveston was awarded two Prevention grants (PP190004, PP210020) totaling $4.5 million to provide cancer prevention services to populations and geographic areas at high risk of HPV-related cancer morbidity and mortality.

The human papillomavirus (HPV) is the most common sexually transmitted infection. About 13 million women and men in the United States acquire HPV each year. Despite effective screening and the implementation of the HPV vaccine, doctors diagnosed more than 13,000 women with cervical cancer in 2020 in the United States, and nearly 4,000 women died from this disease.
In 2014, Abbey Berenson, M.D., Ph.D., professor, Departments of Obstetrics & Gynecology and Pediatrics, and director, Center for Interdisciplinary Research in Women’s Health at The University of Texas Medical Branch at Galveston, initiated a program in the pediatric clinics at UTMB Galveston to increase HPV vaccine uptake among children 9–17 years of age. Her team has found that several factors are associated with low vaccination rates, including race/ethnicity, parental education, marital status, provider recommendation, income, and age.
In the current study, Dr. Berenson and colleagues aimed to examine parental attitudes towards earlier vaccine initiation by interviewing parents of 9–10-year-old children who received vaccination counseling through this program. The secondary aim was to understand parental perspectives on general childhood vaccination and school-based vaccination initiatives to inform potential interventions and improve HPV vaccination rates in Texas.
The data, published in Vaccines on February 27, revealed that many participants preferred starting the HPV vaccine series when their child was a teenager; however, their reasoning varied widely and was not based on scientific fact. Recurrent themes included concerns about vaccine side effects, limited knowledge and exposure to vaccine information, and mistrust in the healthcare system. However, many participants expressed trust in their physicians who bridged the information and trust gap. The team emphasized that they could improve patient vaccine education and uptake through policy and public schooling, empowering physicians to educate patients on the HPV vaccine, and allowing nurses to play an important role in patient education.
The University of Texas Medical Branch at Galveston received a $2.5 million CPRIT Prevention grant (PP190004) in February 2019 to expand the HPV vaccination program to 9–17-year-olds from medically underserved area
