What You Need to Know Before You Apply

What is the purpose of this trial?

This trial aims to find better ways to encourage young adults in Texas to receive the HPV vaccine, which helps prevent certain cancers. Participants will be divided into groups that receive different types of information, such as written stories, videos, or standard information from the CDC. Some participants will also have easier access to the vaccine. The trial focuses on college students who have not yet been vaccinated against HPV. Those between 18 and 26, who can read English, and are enrolled in a participating school might be a good fit. As an unphased trial, this study offers a unique opportunity to contribute to public health by improving vaccination rates among young adults.

Do I need to stop my current medications for this trial?

The trial information does not specify whether you need to stop taking your current medications.

What prior data suggests that the HPV Vaccine is safe for young adults?

Research has shown that the HPV vaccine is generally safe for young adults. The CDC recommends it for everyone up to age 26. Widely used, the vaccine typically causes mild side effects, such as pain, redness, or swelling at the injection site. Occasionally, individuals may feel dizzy or experience a headache after receiving the shot.

Most reported side effects are not serious. The vaccine helps prevent cancers linked to HPV, such as cervical cancer. It has undergone testing and approval, with many people already benefiting from it. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about this trial because it explores different ways to encourage young adults in Texas to get the HPV vaccine, a crucial tool in preventing certain cancers. Unlike standard approaches that typically rely on basic CDC information, this trial tests innovative strategies like video and written narratives to make the information more engaging. Additionally, some groups receive enhanced access to vaccination, which could make it easier for participants to get vaccinated. By examining these varied methods, researchers hope to discover more effective ways to increase HPV vaccination rates and ultimately improve public health outcomes.

What evidence suggests that this trial's treatments could be effective in increasing HPV vaccination rates among young adults in Texas?

Studies have shown that the HPV vaccine effectively prevents infections with the human papillomavirus, which can lead to cervical cancer and other health issues. Research indicates that the vaccine offers strong and long-lasting protection, with evidence supporting its safety and effectiveness for over 15 years. The vaccine protects against HPV types responsible for about 90% of cervical cancers. Additionally, studies have found that the vaccine's benefits extend beyond those who receive it, helping to protect unvaccinated individuals through herd protection. This strong evidence supports the vaccine's role in reducing diseases related to HPV. Participants in this trial will receive different interventions, such as written narratives, video narratives, or enhanced access to the vaccine, to promote HPV vaccination among young adults in Texas. ^{6 7 8 9 10}

Published Research Related to This Trial

A comprehensive analysis of adverse events (AEs) reported to the Vaccine Adverse Event Reporting System (VAERS) identified 3,112 AEs for Cervarix, 31,606 for Gardasil, and 6,872 for Gardasil 9, highlighting the need for ongoing monitoring of vaccine safety.

The study found 46 unique serious adverse events (SAEs) associated with the HPV vaccines, clustered around behavioral, neurological, immune, nervous, and reproductive systems, indicating that while the vaccines are effective, further research is needed to understand the cause-and-effect relationships of these AEs.

The FDA has approved both bivalent and quadrivalent HPV vaccines, which are recommended for routine vaccination in girls aged 11 to 12, and can be given as early as 9 years old, with catch-up vaccination for females aged 13 to 26.

The vaccines are most effective when administered before any sexual activity, but even sexually active individuals can still benefit, as they may not have been exposed to all HPV types covered by the vaccines.

Committee opinion no. 467: human papillomavirus vaccination. [2021]

In a study of 155 women aged 27-45 who tested positive for high-risk HPV and received the Gardasil 9 vaccine, 49% cleared the virus after vaccination, indicating some potential benefit of the vaccine in this age group.

However, the study found no significant differences in risk factors or outcomes between those who cleared the virus and those who did not, suggesting that the vaccine's role as a treatment for existing HPV infections remains uncertain.

The nine-valent HPV (9vHPV) vaccine demonstrated comparable immune responses to the quadrivalent HPV (qHPV) vaccine for HPV types 6/11/16/18, while also effectively eliciting immune responses for five additional oncogenic HPV types (31/33/45/52/58) in a study of 500 men aged 16-26.

Both the 9vHPV and qHPV vaccines exhibited similar safety profiles, indicating that the 9vHPV vaccine is a safe and effective option for preventing a broader range of HPV-related diseases.

The HPV 9-valent vaccine is now approved for adults aged 27-45, but vaccination rates in this age group remain very low, with only 0.00 to 5.56% of respondents vaccinated, despite some individuals potentially benefiting from it.

Women aged 27-45 showed a higher prevalence of unprotected sex and a greater number of sexual partners, yet they had lower awareness of HPV-related cancers, indicating a need for improved education and outreach about HPV vaccination and its benefits.

The new nonavalent HPV vaccine (9vHPV) shows a very strong immune response with nearly 100% seroconversion rates and has a safety profile similar to the quadrivalent vaccine (qHPV), although it may cause more local reactions like swelling, especially when given with other vaccines.

The 9vHPV vaccine offers additional protection against HPV-related cancers, potentially preventing 8% to 18% more cases compared to previous vaccines, but its overall impact will depend on various factors such as duration of protection and population-specific HPV type distribution.

Spotlight on the 9-valent HPV vaccine. Lopalco, PL.[2018]

Expanding HPV vaccination to adults, particularly at cervical cancer screening visits for women and during STI consultations for both sexes, could lead to significant reductions in HPV infection rates, with reductions of about 20% for women and even greater reductions (63% for HPV-16 and 84% for HPV-18) when including male vaccination.

The study suggests that while the impact of vaccinating adult women alone is modest, combining vaccination strategies for both genders during key health consultations is a highly efficient approach to improve HPV prevention and reduce the incidence of related cancers.

The HPV vaccine is crucial for preventing HPV-related diseases, including cancers and genital warts, and is recommended for adolescents aged 11 to 12, with catch-up vaccination available until age 26.

Young adult women (ages 18 to 26) represent a significant group for catch-up vaccination, but barriers such as parental decisions and lack of provider recommendations hinder timely vaccination; thus, targeted interventions are needed to improve vaccine uptake in this population.
