This is a multi-center Phase II randomized study. We plan to enroll 78 patients with biopsy-proven hepatic-limited metastatic colorectal cancer deemed resectable after multi-disciplinary discussion. Eligible patients must have confirmed isolated liver metastases by radiographic imaging of the investigators' choosing. Imaging must include the chest, abdomen, and pelvis regardless of imaging modality chosen. Patients will be randomized to either the control arm or the experimental arm. The control arm will receive mFOLFOX6 every 2 weeks for 4 cycles concurrently with Nivolumab. The experimental arm will first be treated with 2 vaccinations of MVA-BN-CV301 given two weeks apart (Days -28, -14) concurrently with Nivolumab followed by 4 vaccinations of FPV-CV301 given two weeks apart concurrently with mFOLFOX6 and Nivolumab, which will again be administered every 2 weeks for 4 cycles (FPV-CV301, mFOLFOX6 and Nivolumab) After Cycle 4, patients will be re-evaluated for surgical resection by re-staging CT chest, abdomen and pelvis (C/A/P). Patients still considered resectable will undergo surgical resection with the goal of complete resection. Patients who cannot be completely resected will continue to be followed on study, and an additional appropriate candidate will be randomized to the corresponding arm.
We will collect peripheral blood and tumor tissue at the time of surgical resection, if applicable, or by re-biopsy if resection is not possible. Post-operative therapy will begin when patients are deemed ready by their surgical oncologist team. Patients in the control arm will then undergo another 8 cycles of mFOLFOX6 with Nivolumab administered concurrently. Nivolumab will then be administered every four weeks. The experimental arm will receive the same post-operative regimen but including FPV-CV301 boosters given concurrently with mFOLFOX6 and Nivolumab. FPV-CV301 will then be administered every 12 weeks, and Nivolumab every 4 weeks. We will collect peripheral blood for evaluation of correlates upon the completion of therapy. The vaccination approach of initial immunization during the neoadjuvant period followed by FPV-CV301 boosters for two years postoperatively was chosen to optimize the induction of a long-lasting tumor-specific host response. Neoadjuvant vaccination will also allow for analysis of the tumor microenvironment in resection specimens.
Post-therapy patients will be under surveillance per NCCN guidelines with repeat CEA every 3 months for 2 years followed by every 6 months for 1 year (total 3 years), repeat CT of the C/A/P every 3 months for 2 years followed by every 6 months for up to 1 year (total 3 years), and colonoscopy at one year with repetition based on findings at the time of the procedure.

High vs. Standard Dose Flu Vaccine for Transplant Patients
Cincinnati, Ohio
Influenza virus is a significant pathogen in pediatric solid organ transplant (SOT) recipients. However, these individuals respond poorly to standard-dose (SD) inactivated influenza vaccine (IIV). Recent studies have investigated two strategies to overcome poor immune responses in SOT recipients: (1) administration of high-dose (HD)-IIV compared to SD-IIV and (2) two doses of SD-IIV compared to one dose of SD-IIV in the same influenza season. One study compared HD-IIV vs. SD-IIV in adult SOT recipients and noted that HD-IIV was safe and more immunogenic; however, the median post-transplant period was 38 months. A phase I pediatric study comparing a single dose of HD-IIV vs. SD-IIV was safe with higher immunogenicity, but the study was limited by small sample size and median post-transplant vaccine administration was 26 months. In another phase II trial of adult SOT recipients, two doses of SD-IIV one month apart compared to one-dose of SD-IIV revealed modestly increased immunogenicity when given at a median of 18 months post-transplant. Therefore, these studies lack both evaluation in the early post-transplant period and substantive pediatric populations. Additionally, the administration of two-doses of HD-IIV in the same influenza season has not been evaluated in pediatric SOT recipients. Thus, the optimal immunization strategy for pediatric SOT recipients less than 24 months post-transplant is unknown. In addition, immunologic predictors and correlates of influenza vaccine immunogenicity in pediatric SOT recipients have not been well-defined.
The central hypothesis of our proposal is that pediatric SOT recipients 1-23 months post-transplant who receive two doses of HD-quadrivalent inactivated influenza vaccine (QIV) will have similar safety but higher Hemagglutination Inhibition (HAI) geometric mean titers (GMTs) to influenza antigens compared to pediatric SOT recipients receiving two doses of SD-QIV.

Enhanced Vaccination Strategy for Preventive Medicine
Cleveland, Ohio
The goal of this clinical trial is to understand if offering a high touch engagement with healthcare center catered to men and bedside vaccine access in a birthing center increases men's engagement in preventive healthcare. The main questions it aims to answer are:
Does access to vaccinations and overall health education for men lead to increased uptake of vaccines? Does access to vaccinations and overall health education for men lead to increased engagement in overall healthcare of male identifying support persons.
Researchers will compare three arms (one that receives an offer of vaccines at bedside in the birthing clinic, one that receives an information flyer about the importance of preventive care in addition to the offer of vaccines and a third one that receives higher level of engagement from patient liaisons as well as the offer of vaccines at bedside) to see if there is a difference in vaccine uptake and engagement in healthcare

Reduced-Dose HPV Vaccine for Women with HIV
Hamilton, Ontario
There are very little data on human papillomavirus (HPV) vaccination among the 18 million women living with HIV (WLWH) globally, who constitute a population most vulnerable to HPV and the resultant cervical cancer. Particularly, there are no data to date on reduced-dose schedules of nonavalent HPV (9vHPV) vaccination in WLWH and there are very little data on the 9vHPV vaccine in this population overall. It is critical to examine the 9vHPV vaccine in WLWH now because the quadrivalent HPV (4vHPV) vaccine has been discontinued. Additionally, in order to reach the World Health Organization's global goal of cervical cancer elimination, we must determine the role of various HPV prevention strategies in this important population including reduced vaccine dosing which can drastically increase the feasibility of HPV vaccination programs globally.
This randomized clinical trial will enrol WLWH aged 18-45 from across Canada who have not previously received an HPV vaccine. Participants will be randomized 1:1 to receive 3 doses of 9vHPV vaccine at the routine vaccine schedule of 0/2/6 months or 2 doses at an expanded schedule of 0/6 months with a third dose at month 12 to adhere to current recommendations for WLWH. We will compare the immune response generated to two versus three doses of 9vHPV vaccine and will follow participants for 2 years to examine the immune response over time.
This study, which builds upon our team's prior work on HPV vaccination in WLWH, will determine whether two doses of 9vHPV vaccine can be used in WLWH instead of three, and will examine additional aspects of HPV vaccination in WLWH including the immune response to three doses, vaccine safety and efficacy, and attitudes towards self-collected HPV samples in this population. These data will inform global public health policy and programming and will inform the global strategy for cervical cancer elimination.

NuestraSaludSegura Program for COVID-19 Testing and Vaccination
Winston-Salem, North Carolina
Latinx communities are disproportionately affected by the COVID-19 pandemic, with Spanish-speaking Latinx communities carrying even heavier burdens of infection, hospitalization, and mortality. Major barriers to COVID-19 testing and vaccination exist, and a profound need remains to understand and address the social, ethical, and behavioral implications (SEBI) of COVID-19 testing and vaccination within Latinx communities. Our community-academic partnership proposes a rigorous mixed-methods, community-based participatory research study to better understand the SEBI of COVID-19 testing and vaccination and to refine and test a novel and culturally congruent intervention that integrates two evidenced-based strategies - peer navigation and mHealth - to increase COVID-19 testing and vaccination within Spanish-speaking Latinx communities.

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.

Nudge Communication for Flu Vaccination
Bethesda, Maryland
In randomized clinical trials and observational studies, influenza vaccination is effective in reducing influenza-related illness and hospitalizations and potentially cardiovascular (CV) events and mortality in select populations. However, the potential population-level benefit of influenza vaccination is limited by its uptake. Novel implementation strategies to improve vaccination uptake are needed.
KP VACCINATE is a multicenter, sequential, individual-level randomized controlled implementation trial examining the effectiveness of a CV-focused nudging communication vs. usual care communication on influenza vaccination uptake among Kaiser Permanente Northern California (KPNC) and Kaiser Permanente Mid Atlantic States (KPMAS) eligible members during the 2024-2025 influenza season.

High vs Standard Dose Flu Vaccine for Lung Transplant Recipients
Nashville, Tennessee
Lung allograft recipients have a higher burden of influenza disease and greater associated morbidity and mortality compared with healthy controls. Induction and early maintenance immunosuppression is thought to impair immunogenicity to standard dose inactivated influenza vaccine. This early post-transplant period is when immunity is most desirable, since influenza disease during this time frame is associated with adverse consequences. Thus, strategies to reduce severe influenza disease in this highly susceptible population are critical. No trials in lung transplant recipients have evaluated two doses of HD-IIV within the same influenza season as a strategy to improve immunogenicity and durability of influenza prevention. Furthermore, no influenza vaccine trials have focused on enrollment of subjects at early post-transplant timepoints. Very few studies have been performed in solely lung allograft recipients. Immunosuppression intensity is highest in lung patients, thereby limiting comparisons to recipients of heart, liver, and kidney transplants. Therefore, studies to assess both HD-IIV and two-dose strategies in the same influenza season in post-lung transplant recipients are greatly needed.
The central hypothesis of our proposal is that lung allograft recipients who are 1-35 months post-transplant and receiving two doses of HD-quadrivalent inactivated influenza vaccine (QIV) will have higher HAI geometric mean titers (GMT) to influenza antigens compared to those receiving two doses of SD-QIV. To test this hypothesis and address the above critical knowledge gaps, we propose to conduct a phase II, multi-center, randomized, double-blind, controlled immunogenicity and safety trial comparing the administration of two doses of HD-QIV to two doses of SD-QIV in lung allograft recipients 1-35 months post-transplant. The results of this clinical trial will address significant knowledge gaps regarding influenza vaccine strategies (e.g., one vs. two doses and HD-QIV vs. SD-QIV) and immune responses in lung transplant recipients and will guide vaccine recommendations during the post-transplant period.

High vs Standard Dose Flu Vaccine for Solid Organ Transplant Recipients
Nashville, Tennessee
The influenza virus is a significant cause of morbidity in adult solid organ transplant (SOT) recipients. However, these individuals show a suboptimal response to vaccines including the standard-dose (SD) inactivated influenza vaccine (IIV). Recent studies have investigated two strategies to overcome poor immune responses in SOT recipients: (1) administration of high-dose (HD)-IIV compared to SD-IIV and (2) two doses of SD-IIV compared to one dose of SD-IIV in the same influenza season. The first study compared HD-IIV vs. SD-IIV in adult SOT and noted HD-IIV was safe and reported higher immunogenicity; however, the median post-transplant period was 38 months. In another phase II trial of adult SOT recipients, two doses of SD-IIV a month apart compared to one-dose SD-IIV revealed increased immunogenicity, with a median post-transplantation period of 18 months. Therefore, these studies lack evaluation in the early post-transplantation period in this vulnerable population when influenza disease is most severe. The administration of two-doses of HD-IIV in the same influenza season has also not been studied in SOT recipients. Moreover, the vast majority of SOT influenza vaccinations studies have not substantively evaluated prolonged immunogenicity. Thus, the optimal immunization strategy for SOT recipients less than 12 months post-transplant is poorly-defined. In addition, the immunologic predictors and correlates of influenza vaccine immunogenicity in SOT recipients have not been defined. The investigators hypothesize that adult solid organ transplant recipients that are 1-11 months out from transplant and are receiving high-dose inactivated influenza vaccine will have higher hemagglutination inhibition (HAI) geometric mean titers to influenza A antigens compared to adult SOT recipients receiving standard-dose inactivated influenza vaccine. To test this hypothesis and address the above critical knowledge gaps, The investigators propose to conduct a phase II multicenter randomized controlled trial comparing either two doses HD-IIV, two doses of SD-IIV, or one-dose of HD-IIV in adult kidney, heart, and liver SOT recipients 1-11 months post-transplantation. The results of this study will address significant gaps in knowledge regarding influenza vaccine strategies and immune responses in adult SOT recipients and will guide vaccine recommendations in this vulnerable population.

Cancer Survivor Stories for Preventing HPV Cancers
Hershey, Pennsylvania
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).

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.

Typhoid Vaccine for Typhoid
Baltimore, Maryland
This is an open-label, non-randomized study. The purpose of this study is to better understand how vaccines against typhoid fever affect the normal immune system and bacteria in the intestine. Patients having standard-of-care colonoscopies will be divided into 3 groups:
Group 1: Vivotif typhoid vaccination then colonoscopy; Group 2: Colonoscopy, then Vivotif typhoid vaccination, then follow-up colonoscopy; Group 3: Colonoscopy without vaccination.
The Vivotif typhoid vaccine used in this study is 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 vaccine.

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, Cancer Survivor Stories for Preventing HPV Cancers and Enhanced Vaccination Strategy for Preventive Medicine to the Power online platform.
