1,047 Clinical Trials for Various Conditions
The purpose of this phase 1/2 study is to investigate the safety and immunogenicity of different doses (high, medium and low) of a second generation structurally designed (SD2) H5 messenger ribonucleic acid (mRNA) vaccine against pandemic H5 influenza virus (pandemic flu H5 hemagglutinin (HA) mRNA SD2) in healthy younger and older adults. The study will aim to identify the appropriate dose for further clinical development of a potential pandemic response vaccine. The study duration per participant will be approximately 13 months. There will be two injections of placebo or pandemic flu H5 mRNA vaccine 21 days apart at high, medium and low doses. Study visits/contact include: 7 study visits and 1 telephone call. Vaccination visits (including blood samples) will occur at Day 01 and Day 22. Short-term follow-up visits (including blood samples) will occur 8 and 21 days after each injection. Participants will be also followed up (including blood samples) at 3 and 6 months after 2nd injection, and at 12 months after 2nd injection for safety.
The purpose of this study is to evaluate the safety and immunogenicity of a single intramuscular injection of different formulations of a hexavalent influenza messenger ribonucleic acid (mRNA) vaccine composed of differing dose levels of trivalent (TIV) mRNA hemagglutinin (HA) in combination with TIV mRNA-neuraminidase (NA) compared to an active control ((Fluzone standard-dose quadrivalent influenza vaccine (QIV-SD) or Fluzone high-dose quadrivalent influenza vaccine (QIV-HD) in adults 50 years of age and older.
This study will be a 6-month, cluster randomized, pragmatic replication trial to evaluate the effectiveness of personalized nudges to clinicians and patients, relative to a control, to increase flu vaccination rates among older adults in accordance with CDC guidelines. This will include clinician and patient level nudge interventions, with additional, intensified nudge interventions for patients identified as high risk for not receiving a flu vaccine. Among the intervention clinics, patients will receive pre-visit text message reminders about the flu vaccine, and clinicians will receive a default pended order in the visit encounter in the EHR, along with monthly peer comparison feedback about their flu vaccine completion rate. Patients identified as high risk for noncompletion will be individually randomized to receive an additional bidirectional text message nudge or the standard text messaging
The primary objectives of this study are to evaluate the safety and reactogenicity of mRNA-1010, and to evaluate relative vaccine efficacy (rVE) of mRNA-1010 versus an active comparator against reverse transcription polymerase chain reaction (RT-PCR)-confirmed protocol-defined influenza-like illness (ILI) caused by any influenza A or B strains.
The aim of this study is to evaluate the safety, reactogenicity and immunogenicity of the Flu Pandemic messenger RNA (mRNA) vaccine (including dose-finding and dose-confirmation) administered in healthy adults 18 to 85 years of age.
The purpose of this clinical trial is to see if combining a licensed COVID-19 vaccine and a licensed influenza vaccine into a single shot is safe and can help produce antibodies to defend the body against both SARS-CoV-2 (the virus that causes COVID-19) and influenza. Participants enrolled in this trial will be healthy adults, 50 years of age or older.
This Phase 1 study will assess the safety and efficacy (usefulness) of administering 2 doses of seasonal flu vaccine directly into breast cancer tissue (primary tumor), and will study the tumor and whole body response to the vaccine. If the tumor is palpable (able to fee by touch), the vaccine will be administered by a Surgeon/oncologist in the outpatient floor - both experienced and trained. If not palpable, the procedure will be done via guided Ultrasound by our Breast Radiologist -- both experienced and trained. Women with triple-negative (TNBC) and HER2+ types of breast cancer will be eligible for enrollment. Up to 18 subjects may be enrolled at Rush. Successive groups of 3 subjects per breast cancer type will be given increasing doses of vaccine. There are 3 potential dosing groups (half-dose, full dose, and high dose). Blood, stool (optional), and tumor tissue samples will be collected and tested. The active participation period is from one week prior to starting chemotherapy through three months post surgery.
The purpose of this study is to learn about the safety and effects of the study vaccine for the possible prevention of influenza. Influenza is a disease that can spread easily from one person to another and cause body aches, fever, cough, and other symptoms. The study vaccine is called Pandemic Influenza modRNA (pdmFlu) Vaccine. This study is seeking for participants who are: * between the ages of 18 to 49 years old or 65 to 84 years old. * willing and able to follow with all scheduled visits, treatment plan, laboratory tests, lifestyle changes, and other study procedures. * healthy as confirmed by medical history, physical examinations, and the study doctor. * capable of signing informed consent. Participants will receive either: * the pdmFlu vaccine, * a licensed influenza vaccine * a placebo. A placebo does not have any medicine in it but looks just like the study medicine. Participants will not know which vaccine they receive. Participants will receive the study vaccines as a single shot in the arm. The study will compare participant experiences to help understand if the pdmFlu vaccine is safe and effective. Participants will take part in this study for up to 13 months. During this time, the participants will receive the study vaccine and take part in follow-up visits.
This trial is taking place in Los Angeles, CA at 21 clinics within the UCLA Health System. The study design is a 3 arm randomized trial. Patients will be randomized into 1) receiving portal based reminder messages with a video from their PCP encouraging them to receive the influenza vaccine, 2) portal-based reminder messages with an infographic with the image of their PCP encouraging them to receive the influenza vaccine, or 3) the control group. Patients randomized to the intervention arms will receive reminders if they are due for influenza vaccine. Despite the Advisory Committee on Immunization Practices (ACIP) recommendation in 2010 that all people above 6 months of age should receive an annual flu vaccine, vaccination rates remain low: at 6m-4.9 yrs. (70%), 5-17.9 yrs. (56%), 18-64.9 yrs. (38%), and \>65 yrs. (63%). The investigators will assess the effectiveness of MyChart R/R video messages and infographic messages as compared to the standard of care control (Health system messages).
This study will be a multisite, cluster randomized, pragmatic trial to evaluate the effectiveness of personalized nudges to clinicians and patients, relative to a control, to increase flu vaccination rates among older adults in accordance with CDC guidelines. This will include clinician and patient level nudge interventions, with an additional, intensified nudge intervention for patients identified as high risk for not receiving a flu vaccine. Among the intervention clinics, patients will receive pre-visit text message reminders about the flu vaccine, and clinicians will receive a default pended order in the visit encounter in the EHR, along with monthly peer comparison feedback about their flu vaccine completion rate. Patients identified as high risk for noncompletion will be individually randomized to receive an additional bidirectional text message nudge or the standard text messaging.
The goal of this research is to increase influenza vaccine acceptance and uptake in vulnerable populations whose primary (and often only) health care access occurs in emergency departments (ED Usual Source of Care Patients). Toward this goal, the investigators will conduct one on one interviews and focus groups with ED Usual Source of Care Patients and community partners and produce trusted messaging informational platforms (PROmotion of FLU VA(X)ccination in the Emergency Department - PROFLUVAXED) that will address barriers to flu vaccination, especially vaccine hesitancy. The investigators will then conduct a cluster-randomized, controlled trial of PROFLUVAXED platforms in six EDs to determine whether their implementation is associated with greater flu vaccine acceptance and uptake in ED Usual Source of Care Patients.
This study includes 3 parts: Parts A, B, and C. The purpose of this study is to evaluate the immunogenicity and safety of mRNA-1010 seasonal influenza vaccine in adults.
Substudy A: This is a Phase 1 randomized, open-label study to describe the safety and immunogenicity of up to 3 dose- level combinations of modRNA quadrivalent influenza vaccine (qIRV (22/23)) and bivalent BNT162b2 (original/Omi BA.4/BA.5). Participants will receive either: * qIRV (22/23)/bivalent BNT162b2 (original/Omi BA.4/BA.5), at 1 of the 3 dose-level combinations * qIRV (22/23) at dose level 1, * qIRV (22/23) at dose level 2, or * bivalent BNT162b2 (original/Omi BA.4/BA.5) at dose level 1 administered concurrently in the opposite arm to commercially licensed quadrivalent influenza vaccine (QIV). Substudy B: This Phase 1/2 study will describe the safety, tolerability, and immunogenicity of quadrivalent influenza vaccine (qIRV)/bivalent BNT162b2 (original/Omi BA.4/BA.5), trivalent influenza vaccine (tIRV)/bivalent BNT162b2 (original/Omi BA.4/BA.5), and bivalent influenza vaccine (bIRV)/bivalent BNT162b2 (original/Omi BA.4/BA.5) when given concurrently with licensed quadrivalent influenza vaccine (QIV).
The purpose of this study is to evaluate the safety and efficacy of mRNA-1010 in preventing seasonal influenza in adults 50 years and older.
This is a Phase 3, randomized, observer-blinded study to evaluate the efficacy, safety, tolerability, and immunogenicity of a single dose of a quadrivalent influenza modRNA vaccine compared to licensed inactivated influenza vaccine in healthy adults 18 years of age and older.
This trial is taking place in Los Angeles, CA at clinics within the Los Angeles Department of Health clinics. The study design is a comparative effectiveness trial design. Patients will be randomized into 1) receiving enhanced texting with a callback by a trained call-center staff member to schedule a vaccine visit if the patient presses "1" in response to the text, 2) receiving enhanced bidirectional texting with a texting response from a trained call-center staff member who will help the patient schedule a vaccine visit through a series of back-and-forth texts, or 3) standard text reminders (control group). Patients in all arms will receive reminders if they are due for influenza vaccine. Despite the Advisory Committee on Immunization Practices (ACIP) recommendation in 2010 that all people above 6 months of age should receive an annual flu vaccine, vaccination rates remain low: at 6m-4.9 yrs. (70%), 5-17.9 yrs. (56%), 18-64.9 yrs. (38%), and \>65 yrs. (63%). The investigators will assess the effectiveness of enhanced text R/R messages as compared to the standard of care control (standard text reminders).
This trial is taking place in Los Angeles, CA at clinics within the UCLA Health System. The study design is a 2x2 nested factorial design. Patients will be randomized into 1) receiving text based reminder messages with direct scheduling link, 2) portal-based reminder messages with direct scheduling link, or 3) the control group. Patients randomized to the intervention arms will receive reminders if they are due for influenza vaccine. Nested within the portal reminder arm, we will have two additional components for which patients will be randomized separately: 1. A pre-commitment prompt, asking patients which time (September, October, November or December) and which place (UCLA, pharmacy, workplace or school, or other) they plan to get their Influenza vaccine with tailored monthly messages based on responses (pre-commitment message with tailored recall messages with direct scheduling vs. standard portal reminders with direct scheduling). 2. A pre-appointment reminder encouraging patients to ask for their influenza vaccine at their upcoming appointment (pre-appointment reminder encouraging influenza vaccination vs. standard pre-appointment reminder not mentioning influenza vaccination) Nested within the text message reminder arm, we will have one additional component for which patients will be randomized separately: 1) A pre-appointment reminder encouraging patients to ask for their influenza vaccine at their upcoming appointment (pre-appointment reminder encouraging influenza vaccination vs. standard pre-appointment reminder not mentioning influenza vaccination) Despite the Advisory Committee on Immunization Practices (ACIP) recommendation in 2010 that all people above 6 months of age should receive an annual flu vaccine, vaccination rates remain low: at 6m-4.9 yrs. (70%), 5-17.9 yrs. (56%), 18-64.9 yrs. (38%), and \>65 yrs. (63%). The investigators will assess the effectiveness of MyChart R/R messages and text R/R messages as compared to the standard of care control (no messages).
This study will test the relative efficacy of high-risk messages in increasing flu shot rates in patients at moderately high risk for flu and complications (those in the top 11-20% of risk). It will also examine whether informing patients that their high-risk status was determined by analyzing their medical records or by an artificial intelligence (AI) / machine-learning (ML) algorithm analyzing their medical records will affect the likelihood of receiving a flu vaccine.
This is a Phase 2, randomized, multi-center study in approximately 300 adults who received 2 doses of aH5N1c or placebo in and completed the parent study V89_18 in the \<65 years of age cohort. The study investigates whether two priming doses of MF59-adjuvanted H5N1 cell culture-derived vaccine (aH5N1c) followed by one or two booster vaccinations with a MF59-adjuvanted H5N6 cell culture derived vaccine (aH5N6c) 3 weeks apart elicit immune responses to the antigens used for priming (H5N1) and boosting (H5N6) after first and second heterologous booster vaccination. Eligible subjects, who received 2 doses of aH5N1c in the parent study V89_18 are randomized in a 1:1 ratio to receive either two aH5N6c vaccinations, 3 weeks apart (group 1) or an aH5N6c vaccination on Day 1 and saline placebo on Day 22 (group 2). Eligible subjects, who received placebo in the parent study will receive two aH5N6c vaccinations, 3 weeks apart (group 3). After the second vaccine administration, subjects are monitored for approximately 6 months for safety and antibody persistence. The total study duration will be approximately 7 months per subject.
The purpose of this clinical trial is to evaluate the safety and immunogenicity of BW-1014. BW-1014 is a nanoemulsion (NE) adjuvanted recombinant Hemagglutinin 5 (rH5) that would protect against pandemic flu. The study will be conducted in 40 healthy adults volunteers, age 18 - 45, in one center in the United States. The study will compare 3 different dose levels of rH5 (25µg, 50µg and 100µg rH5 in 20% NE adjuvant using a pipette dropper with rH5 control (100µg without NE adjuvant) and placebo control (saline). The investigational product will be administered in 2 doses intranasally (IN). This will be followed 6 months later with a licensed H5N1 IIV IM vaccine. In addition to safety outcome, homologous and heterologous immunological outcomes will be tested in nasal wash, serum, and blood cells.
The purpose of this clinical trial is to learn about the safety and effects of the study vaccine for the potential prevention of influenza. The study vaccine is called Self-Amplifying Ribonucleic Acid vaccine (saRNA vaccine). This study is seeking participants who: * Are between the age of 18 to 49 years old. * Are willing and able to comply with all scheduled visits, treatment plan, laboratory tests, lifestyle considerations, and other study procedures. * Are healthy as determined by medical history, physical examinations, and the study doctor. * For male participants, can father children and willing to use an acceptable method of contraception. Female participants who are not of childbearing potential; or male participant not able to father children. * Are capable of giving signed informed consent. Participants will receive either the saRNA vaccine, a licensed Influenza Vaccine (QIV) or a placebo. Participants will not know which vaccine they receive in advance. A placebo does not have any medicine in it but looks just like the study medicine. Participants will receive the study vaccines as a single shot in the arm. We will compare participant experiences to help us determine if the saRNA vaccine is safe and effective. Participants will take part in this study for 6 months. During this time, they will receive the study vaccine and participate in follow-up visits.
This study will be divided into two substudies - Substudy A (SSA) and Substudy B (SSB) Substudy A This is a Phase 1 randomized substudy to evaluate the safety and immunogenicity of monovalent influenza modRNA vaccine (mIRV) and bivalent influenza modRNA vaccine (bIRV) at various dose levels, and quadrivalent influenza modRNA vaccine (qIRV), in participants 65 to 85 years of age. Participants will receive at Vaccination 1 either: * 1 of 4 dose levels of mIRV (either A or B Strain), * 1 of 4 dose levels of bIRV (containing both A and B strains), * qIRV (at 1 dose level), or * A licensed quadrivalent influenza vaccine (QIV). At approximately 8 weeks following Vaccination 1, participants will be unblinded and QIV (Vaccination 2) administered to participants not having previously received this at Vaccination 1. Additionally, participants who previously received QIV at Vaccination 1 will receive one of the following for Vaccination 2: * mIRV encoding A strain at dose level 4, or * mIRV encoding B strain at dose level 4. Substudy B This is a randomized substudy to evaluate the safety and immunogenicity of the following vaccination schedules in participants 65 to 85 years of age: 2-Visit Schedules * 2 doses of qIRV (at a dose level 1), administered 21 days apart. * 2 doses of licensed QIV, administered 21 days apart (as a control group) * A dose of licensed QIV following by a dose of bIRV encoding 2 A strains at dose level combination 1 or 2, administered 21 days apart. 1-Visit Schedules * A dose of licensed QIV administered concurrently in the opposite arm with bIRV encoding 2 A strains at dose level combination 1 or 2. * A dose of bIRV encoding 2 A strains administered concurrently in the opposite arm with a dose of bIRV encoding 2 B strains.at dose level 1. * A dose of qIRV encoding 2 A strains and 2 B strains at dose level 2 (at one of two possible dose level combinations). * A dose of qIRV encoding 2 A strains and 2 B strains at dose level 3. * 1 dose of licensed QIV (as a control group). Substudy B In participants 18 to 64 years of age: -A dose of qIRV encoding 2 A strains and 2 B strains at a dose level combination 1 or 2.
This trial is taking place in Los Angeles, CA at clinics within the UCLA Health System. The study design is a 2x2 nested factorial design. Patients will be randomized into 1) receiving text based reminder messages, 2) portal-based reminder messages or 3) the control group. Patients randomized to the intervention arms will receive reminders if they are due for influenza vaccine. Nested within the reminder arms (text or portal), we will have 2 additional components for which patients will be randomized separately: * A direct scheduling link within the reminder letter enabling the patient to schedule an influenza vaccine only visit (direct scheduling link vs. no direct scheduling link). * A pre-appointment reminder, encouraging patients to ask for their influenza vaccine at their upcoming appointment (pre-appointment reminder encouraging influenza vaccination vs. standard pre-appointment reminder not mentioning influenza vaccination) Despite the Advisory Committee on Immunization Practices (ACIP) recommendation in 2010 that all people above 6 months of age should receive an annual flu vaccine, vaccination rates remain low: at 6m-4.9 yrs. (70%), 5-17.9 yrs. (56%), 18-64.9 yrs. (38%), and \>65 yrs. (63%). The investigators will assess the effectiveness of MyChart R/R messages and text R/R messages as compared to the standard of care control (no messages).
The aim of this study was to evaluate the immune response and safety of both GlaxoSmithKline Biologicals SA's (GSK's) herpes zoster (HZ) subunit (su) vaccine in healthy adults 50 years of age (YOA) and older and quadrivalent seasonal influenza (Flu D-QIV) vaccine in healthy adults 18 YOA and older, when administered sequentially or co-administered with Moderna's mRNA-1273 booster vaccination against COVID-19.
The purpose of this study is to evaluate the clinical lot-to-lot consistency of the respiratory syncytial virus (RSV) maternal (RSV MAT) vaccine administered to healthy non-pregnant women 18-49 years of age (YOA). In addition, this study will evaluate immunogenicity, safety and reactogenicity from co-administration of RSV MAT vaccine and GSK's quadrivalent seasonal influenza (Flu D-QIV) vaccine.
Background: Influenza (flu) is a virus that infects people of all ages. Some people may have mild flu symptoms. Others may get very sick and even die from the flu. Flu vaccines help protect people against the flu, but if the flu strains in the vaccine are not a good match with the strains circulating in the community, the vaccine is not as effective. Researchers want to make flu vaccines that protect against changing flu strains. Objective: To test if a new flu vaccine is safe and if it creates an immune response. Eligibility: Healthy adults ages 18-55 who do not smoke and have not received a flu vaccine in the 8 weeks prior or a COVID-19 vaccine in the 4 weeks prior to enrollment. Design: Participants will be screened on a separate protocol. Participants will have 9 visits over 7 months. They will get a combination of study vaccine and/or placebo, both as a shot in the arm and as a spray into the nose, at 2 visits. For 7 days after getting the vaccines, they will take their temperature and complete online surveys at home to record any symptoms. At each visit, participants will have a physical exam and medical history. They will give blood and urine samples. They will have nasal testing. For this, a thin absorptive strip will be inserted into their nostril for 1 minute to collect mucus. At some visits, the inside of their nose will be wiped with a small brush to collect cells. For this, their nostril will be numbed to make it more comfortable. Some blood and nasal samples will be used for genetic testing. Participants who get flu-like symptoms during the study will be asked to collect nasal samples at home and send these samples back to NIH to test if they actually have the flu.
The study team previously demonstrated that patients are more likely to receive flu vaccine after learning that they are at high risk for flu complications. Building on this past work, the present study will explore whether providing reasons that patients are considered high risk for flu complications (a) further increases the likelihood they will receive flu vaccine and (b) decreases the likelihood that they receive diagnoses of flu and/or flu-like symptoms in the ensuing flu season. It will also examine whether informing patients that their high-risk status was determined by analyzing their medical records or by an artificial intelligence (AI) / machine-learning (ML) algorithm analyzing their medical records will affect the likelihood of receiving the flu vaccine or diagnoses of flu and/or flu-like symptoms.
Background: Influenza (flu) is a contagious respiratory illness. It is caused by influenza viruses that infect the nose, throat, and sometimes the lungs. Vaccines are given to teach the body to prevent or fight infection. Researchers want to study a new vaccine to prevent the seasonal flu. Objective: To see if the FluMos-v1 vaccine is safe and how the body responds to it. Eligibility: Healthy adults ages 18-50 years inclusive were enrolled. Design: Participants were screened through a separate protocol. Participants were tested for COVID-19. They may have had a pregnancy test. Participants received the investigational FluMos-v1 vaccine or the licensed inactivated seasonal quadrivalent influenza vaccine Flucelvax injected in the upper arm. Participants completed a diary card for 7 days. They recorded any symptoms they had. They were given a thermometer to check their temperature. They were also given a ruler to measure any skin changes at the injection site. Participants had about 10 study visits. They were asked how they were feeling and if they had taken any medications. They had blood drawn. Some participants had an optional apheresis. Blood was removed through a needle in a vein in one arm. A machine separated the white blood cells. The rest of the blood was returned through a needle in a vein in the other arm. Participation lasted for 40 weeks.
The purpose of this study is to measure immunity to the flu vaccine over time in patients who have had COVID-19 and may have other medical conditions including obesity, type 2 diabetes, chronic fatigue, or long-term COVID-19 symptoms. Adults and children (age 13 to 64) who had been diagnosed with COVID-19 as well as controls without COVID-19 will be invited to participate in this study.
Background: The flu is a common viral infection that can be deadly for certain people. Vaccines against flu have been developed to teach the body to prevent or fight the infection. A new vaccine may help the body to make an immune response to H10 flu, a flu strain that infects humans. Objective: To test the safety and effectiveness of the H10 Stabilized Stem Ferritin vaccine (VRC-FLUNPF0103-00-VP or H10ssF-6473). Eligibility: Healthy adults ages 18-70, but not born between 1965-1970 Design: Participants received 1 or 2 vaccinations by injections (shots) in the upper arm muscle over 4 months. Participants received a thermometer and recorded their temperature and symptoms every day on/with/via a diary card for 7 days after each injection. The injection site was checked for redness, swelling, itching or bruising. Participants had 8-10 follow-up visits over 10 months. At follow-up visits, participants had blood drawn and were checked for health changes or problems. Participants who reported influenza-like illness had nose and throat swabs collected for evaluation of viral infection. Some participants had apheresis. A needle was placed into a vein in both arms. Blood was removed through a needle in the vein of one arm. A machine removed the white blood cells and then the rest of the blood was returned to the participant through a needle in the other arm.
