This randomized controlled trial (RCT) evaluates the association of a narrative communication intervention on human papillomavirus (HPV) vaccination rates among 9- to 12-year-olds. The intervention is a brief video from local cancer survivors narrating their stories with an HPV-related cancer diagnosis and recommending the HPV vaccine for cancer prevention. RCT participants will be the parents (n=200) of children ages 9-12 who have not initiated HPV vaccination. Participants will be randomized (1:1) to our intervention or control (placebo video) one week before their child's next primary care visit. Our primary outcome is HPV vaccine initiation (first dose of the HPV vaccine series) among children ages 9-12 at the time of the wellness visit. The study also explores the effect of narratives on theory-based mediators of HPV vaccination, including parents' cognitive (e.g., risk perception) and emotional reactions (e.g., hope, anticipated regret).

This is an open-label, non-randomized study. The purpose of this study is to better understand how vaccines against typhoid fever and cholera affect the normal immune system and bacteria in the intestine. Patients having standard-of-care endoscopies (colonoscopy and/or esophagogastroduodenoscopy (EGD)) will be divided into 3 groups: Group 1: Vivotif typhoid vaccination and/or Vaxchora cholera vaccination then endoscopy Group 2: Endoscopy, then Vivotif typhoid vaccination and/or Vaxchora cholera vaccination, then follow-up endoscopy Group 3: Endoscopy without vaccination. Both vaccines used in this study are licensed by the Food and Drug Administration (FDA) for travelers to developing countries. Volunteers will be asked to donate tissue, blood, saliva and stool samples for studying how the body responds to the typhoid and/or cholera vaccine.

This project aims to evaluate the Help Wanted Prevention Intervention, an online program to provide people with a sexual attraction to children the skills and resources to support their commitment to keep children safe and to improve the participants well-being. In phase one, ten men with a sexual attraction to children who have never had a contact offense with a child will be asked to go through an abbreviated version of the participant procedures that will be used in study phase two (described next). Specifically, the ten participants will complete one of the online surveys, review the Help Wanted program, and participate in a 30-60 minute anonymous audio call with a member of the study team to provide feedback on the study procedures and materials (e.g., consent form, recruitment form). Feedback from phase one will inform changes to study procedures for phase two. Phase two consists of a large-scale evaluation of the Help Wanted program. Three hundred men with a sexual attraction to children who have never had a contact offense with a child or accessed the Help Wanted Program will be randomly selected to be part of one of two groups: the program group (N = 200) or the control group (N = 100). Both groups will be asked to complete an online survey before reviewing the Help Wanted Program, provide feedback on the program over a one-month period, and complete another online survey immediately after reviewing the program and three months after reviewing the program. Participants in the control group will have a one month waiting period after the first online survey, during which the participants will receive alternative resources and supports for mental health and sexual attraction to children. After the one month waiting period, participants in the control group will complete one additional online survey before reviewing the Help Wanted program and completing the two final online surveys (one immediately after reviewing the program, one three months after reviewing the program). Survey questions will ask about participants thoughts, feelings, and behaviors, including questions about the participants overall well-being and sexual attraction to children. All study materials and resources are in English. Resources provided to participants are also in English, but provide services in over 30 countries to include participants who may reside in countries outside of the United States. Participation is anonymous and all data will be kept confidential.

The goal of this clinical trial is to test if virtual facilitation (e.g., video coaching) increases rural pharmacists' ability to implement COVID-19 vaccine hesitancy counseling when compared to a "standard" implementation approach (e.g., training and dissemination of implementation support tools) in rural pharmacies. The main question it aims to answer is if virtual facilitation improves fidelity to a newly developed vaccine hesitancy counseling intervention when compared to standard implementation. All participants will begin in the standard implementation condition, where they will complete a webinar on COVID-19 vaccinations and a 30-minute online training on vaccine hesitancy communication. After standard implementation, they will switch to the virtual facilitation condition where they will be assigned a virtual coach to help them with implementing the intervention. There will be six fidelity observations per each 8-week intervention period to determine whether pharmacists are implementing the intervention as intended. Researchers will compare fidelity between the standard and virtual facilitation conditions.

Central hypothesis: a multimodal approach is needed to enhance RSV vaccine uptake in pregnancy rather than the current standard of care that relies solely on physician recommendations at routine prenatal visits and/or mass messaging to the public. The investigators propose a pilot sequential multiple assignment randomized trial (SMART) to evaluate the effectiveness of a bundle of evidence-based and sequential strategies to test early (28-30 weeks gestation) and late (34-36 weeks gestation efficacy) to increase RSV vaccination during pregnancy.

More than 80% of the 3 million women who labor and deliver each year in the United States undergo continuous electronic fetal monitoring (EFM) during labor in order to fetal hypoxia and prevent the transition to acidemia, expedited operative delivery, and/or neonatal morbidity. Category II EFM is the most commonly observed group of fetal heart rate features in labor. One common response to Category II EFM is maternal oxygen (O2) supplementation. The theoretic rationale for O2 administration is that it increases O2 transfer to a hypoxic fetus. There are conflicting national guidelines regarding O2 administration - the American College of Obstetricians and Gynecologists suggest O2 is ineffective, whereas the Association of Women's Health, Obstetric, and Neonatal Nurses recommend continued use given lack of definitive data on safety and efficacy. A recent national survey of nearly 600 Labor \& Delivery providers in February 2022 revealed that 49% still use O2 . Thus, there remains equipoise on the topic and high-quality data on the safety of intrapartum O2 is needed. None of the trials to date have studied the effect of intrapartum O2 on important clinical measures of neonatal or maternal morbidity. This safety data is imperative because the field of obstetrics must hold supplemental O2 to the same rigorous standards applied to any drug used in pregnancy. Without data on these definitive outcomes, it will be challenging to implement evidence-based recommendations for supplemental O2 use on Labor \& Delivery. The investigators will conduct a large, multicenter, randomized noninferiority trial of O2 supplementation versus room air in patients with Category II EFM in labor.

The goal of the study is to determine the effect of a communications campaign sharing wastewater surveillance data to influence vaccine uptake in a metropolitan and non-metropolitan environment. The study will be conducted in Onondaga and Cayuga counties in New York State. Individuals of all ages within the selected counties, located in metropolitan and non-metropolitan environments will receive the intervention. The evaluation study design is a comparison-control trial. The primary outcome measure is the proportion of vaccine-eligible individuals in the county that received the COVID-19 vaccine stratified by type of vaccine dosage and age group. Vaccination data will be aggregated to the county by the State Department of Health and shared with the research team. Wastewater data will be pulled from the wastewater surveillance network. A difference in differences analysis will be used to estimate the effect of the intervention on both the outcomes between intervention and comparison groups following the intervention, while adjusting for potential confounding factors.

This clinical trial aims to investigate how exposure to Perfluorononanoic acid (PFNA), a type of per- and polyfluoroalkyl substance (PFAS), affects the immune response to the standard tetanus and diphtheria (Td) vaccine. The study focuses on participants from a community with known prior PFNA exposure through contaminated drinking water. The main question it aims to answer is: * Does exposure to PFNA weaken the body's initial immune response, leading to lower levels of protective antibodies after vaccination? Participants will: * Receive Tetanus and Diphtheria (Td) booster vaccination * Visit the study office 7 times over a 30-day period * Have blood and saliva collected at each study visit

"I was diagnosed with stage 4 pancreatic cancer three months ago, metastatic to my liver, and I have been receiving and responding well to chemotherapy. My blood work revealed that my tumor markers have gone from 2600 in the beginning to 173 as of now, even with the delay in treatment, they are not going up. CT Scans reveal they have been shrinking as well. However, chemo is seriously deteriorating my body. I have 4 more treatments to go in this 12 treatment cycle. I am just interested in learning about my other options, if any are available to me."

Social technologies for health have already become essential means for providing underserved populations greater social connectedness and increased access to novel health information. However, these technologies have also had negative unintended consequences. The resulting digital divide in social technology takes many forms - from explicit racism that excludes African American and Latinx populations from the resources enjoyed by White and Asian members of online communities, to self-segregation for the purposes of identity preservation and community-building that unintentionally results in limited informational diversity in underserved communities. The result is an often unnoticed, but highly consequential compounding of inequities. This research seeks to use an online social network approach to address these challenges, in which the investigators demonstrate how reducing the online levels of network centralization and network homophily among African American community members directly increases their productive engagement with health-promoting information.

The goal of this clinical trial is to investigate the safety and tetanus antibody response to a Tdap vaccine in healthy plasma donors. The main question it aims to answer are: * Is it safe to give this vaccine multiple times over one year to plasma donors since the package insert for this vaccine indicates that it should administered once every 10 years? * What is the tetanus antibody response over time in these donors after receiving the vaccine multiple times during the study? Participants will receive a Tdap vaccination every 3 months ±2 weeks for 12 months (5 vaccinations) with a 6 month follow-up after the last vaccination. After obtaining informed consent and screening for eligibility including plasmapheresis donor eligibility, subjects will have other baseline assessments performed and if eligible, will receive the scheduled vaccinations, will be assessed for adverse events (AEs) and have plasma samples collected for antibody titers each month thereafter for 11 months, and then at 1 and 6 months after the last vaccination. As these subjects are participating in a standard donor plasmapheresis donor program, assessments for donor eligibility and routine plasmapheresis will be performed; however, only the data specifically required to meet the objectives of this study will be collected.

People living with HIV (PLWH) are 28 times more likely to be diagnosed with Human Papillomavirus (HPV) - associated anal cancer than the general population. The HPV vaccine is an effective and safe approach to prevent and reduce the risk of HPV-related disease among PLWH. HPV vaccine programs tailored and implemented in the HIV population are lagging for this high-risk group. The CDC's 4 Pillars Transformation Program is a multi-level, evidence-based intervention that has been successfully used to increase HPV vaccination in the general population and is ready to be tested in the high-risk HIV population, particularly PLWH in the rural South. This program offers providers and clinic staff evidence-based strategies to increase HPV vaccination uptake via training and educational resources. This study proposes to tailor and refine the 4 Pillars Program and conduct this project in three HIV clinics in Georgia.

Frequently Asked Questions

How much do Vaccinations clinical trials pay?

Each trial will compensate patients a different amount, but $50-100 for each visit is a fairly common range for Phase 2–4 trials (Phase 1 trials often pay substantially more). Further, most trials will cover the costs of a travel to-and-from the clinic.

How do Vaccinations clinical trials work?

After a researcher reviews your profile, they may choose to invite you in to a screening appointment, where they'll determine if you meet 100% of the eligibility requirements. If you do, you'll be sorted into one of the treatment groups, and receive your study drug. For some trials, there is a chance you'll receive a placebo. Across Vaccinations trials 30% of clinical trials have a placebo. Typically, you'll be required to check-in with the clinic every month or so. The average trial length for Vaccinations is 12 months.

How do I participate in a study as a "healthy volunteer"?

Not all studies recruit healthy volunteers: usually, Phase 1 studies do. Participating as a healthy volunteer means you will go to a research facility several times over a few days or weeks to receive a dose of either the test treatment or a "placebo," which is a harmless substance that helps researchers compare results. You will have routine tests during these visits, and you'll be compensated for your time and travel, with the number of appointments and details varying by study.

What does the "phase" of a clinical trial mean?

The phase of a trial reveals what stage the drug is in to get approval for a specific condition. Phase 1 trials are the trials to collect safety data in humans. Phase 2 trials are those where the drug has some data showing safety in humans, but where further human data is needed on drug effectiveness. Phase 3 trials are in the final step before approval. The drug already has data showing both safety and effectiveness. As a general rule, Phase 3 trials are more promising than Phase 2, and Phase 2 trials are more promising than phase 1.

Do I need to be insured to participate in a Vaccinations medical study?

Clinical trials are almost always free to participants, and so do not require insurance. The only exception here are trials focused on cancer, because only a small part of the typical treatment plan is actually experimental. For these cancer trials, participants typically need insurance to cover all the non-experimental components.

What are the newest Vaccinations clinical trials?

Most recently, we added Educational Program for HPV Vaccination Confidence, Enhanced Vaccination Strategy for Preventive Medicine and Cancer Survivor Stories for Preventing HPV Cancers to the Power online platform.
