This randomized phase III trial studies Tokyo-172 strain bacillus Calmette-Guerin (BCG) solution with or without a vaccination using Tokyo-172 strain BCG to see how well it works compared with TICE BCG solution in treating patients with bladder cancer that has not spread to muscle. BCG is a non-infectious bacteria that when instilled into the bladder may stimulate the immune system to fight bladder cancer. Giving different versions of BCG with vaccine therapy may prevent bladder cancer from returning. Read Less

The primary objectives of the study are: To assess the safety profile of the study vaccines in each study intervention group. To assess the neutralizing antibody profile after primary series vaccination in SARS-CoV-2-naïve adults. To demonstrate that a booster dose of monovalent or bivalent SARS-CoV-2 vaccine given to adults previously vaccinated with an authorized/approved COVID-19 vaccine induces an immune response that is non-inferior to the response induced by a twodose priming series with the monovalent vaccine, and superior to that observed immediately before booster. The secondary objectives of the study are: To assess the neutralizing and binding antibody profiles after primary series vaccination at pre-defined time points during the study. To assess the neutralizing and binding antibody responses of booster vaccination. To describe the occurrences of laboratory-confirmed symptomatic COVID19 after primary series and booster vaccination. To describe the occurrences of serologically-confirmed SARS-CoV-2 infection after primary series vaccination. Read Less

The purpose of this study is to learn if modified RNA (modRNA) vaccines for the prevention of influenza are: * safe; and * how these vaccines produce an immune response in generally healthy adults. Immune response is the way the body protects itself against things it sees as harmful or foreign. RNA (also called ribonucleic acid) is one of two types of nucleic acid made by cells. RNA contains information that has been copied from DNA (the other type of nucleic acid). Cells make several different forms of RNA, and each form has a specific job in the cell. Many forms of RNA have functions related to making proteins. RNA is also the genetic material of some viruses instead of DNA. RNA can be made in the laboratory and used in research studies. Also called ribonucleic acid. Influenza is term used for flu illness. It is an infection caused by a virus that affects your mouth, nose, and throat. The study is seeking for participants who: * are at least 18 years of age * have not received an influenza vaccine within the last 6 months * are generally healthy This study will be divided into three sub-studies: Substudy A (SSA), Substudy B (SSB), and Substudy C (SSC). All participants, regardless of sub-study, will receive 1 dose of either of the following vaccines as an injection into their arm: * 1 of the modRNA influenza vaccines that is being studied; or * an approved influenza vaccine approved for use in their respective age group. Participants will be involved in this study for about 6 months. During this time, participants will have at least 3 clinic visits. Read Less

This study is designed to provide data on the immune response and safety of administering vaccines to relapsing multiple sclerosis (RMS) participants taking ozanimod compared to controls taking interferon-beta's or receiving no disease modifying therapies (DMTs). The data of this study will support the labels for ozanimod in multiple sclerosis (MS) because the effect of ozanimod on the vaccination response of MS participants is of interest to participants and prescribers.

The purpose of this study is to understand the safety and effects of a combined influenza and COVID-19 vaccine. This combined vaccine is compared to separate vaccines for the protection against influenza and SARS-CoV-2. Influenza and COVID-19 are diseases that can spread easily from one person to another and cause body aches, fever, cough, and other symptoms. Giving both influenza and COVID-19 vaccines together against influenza and SARS-CoV-2 could provide great benefits to both patients and caregivers in terms of simple and easy care. Around 8550 participants will be assigned into 1 of 8 vaccination groups (Group A, B, C, D, E, F, G or H) by chance. Cohort 1: Approximately 450 participants will be assigned by chance to one of the following: * Group A:Influenza and COVID-19 combination A vaccine, given at the same time in one arm and placebo (an injection consisting of just salt water and no medicines in it) in the opposite arm. * Group B: COVID-19 vaccine, given at the same time to one arm and licensed influenza vaccine in the opposite arm. Cohort 2: Approximately 4500 participants will be assigned by chance to one of the following: * Group C: Influenza and COVID-19 combination B vaccine, given at the same time in one arm and placebo in the opposite arm. * Group D: COVID-19 vaccine, given at the same time in one arm and licenced influenza vaccine in the opposite arm. Cohort 3: Approximately 3600 participants will be assigned by chance to one of the following: * Group E: Influenza and COVID-19 combination B vaccine. * Group F: COVID-19 vaccine. * Group G: Licenced influenza vaccine. * Group H: Investigational influenza vaccine. All participants in cohort 1 and cohort 2 will receive 2 injections and participants in cohort 3 will receive 1 injection as per their assigned study group at Visit 1. The participants will be followed for about 6 months. During this time, researchers will assess safety and the body's reaction to the vaccination over approximately 6 months. This will help understand if the study medicine is safe. Read Less

This is a prospective, single-arm study designed to understand the mechanisms that lead to a loss of response to influenza vaccine in older adults. The investigators will recruit and longitudinally follow a cohort of 75 older adults (65 years and older) who will receive three different influenza vaccines over three annual influenza seasons. Blood samples will be collected from the participants at sixteen study visits over three years. Nasal swab and stool samples will also be collected from participants at seven time-points across the study period. The study is not designed to assess safety or tolerability of the influenza vaccines administered as part of this study. Read Less

This is a Phase 1/2/3 study in healthy children. Dependent upon safety and/or immunogenicity data generated during the course of this study, and the resulting assessment of benefit-risk, the safety, tolerability, and immunogenicity of BNT162b2 in participants \<6 months of age may subsequently be evaluated.

This phase II trial studies how well TPIV100 and sargramostim work in treating patients with HER2 positive, stage II-III breast cancer that has residual disease after chemotherapy prior to surgery. It also studies why some HER2 positive breast cancer patients respond better to chemotherapy in combination with trastuzumab and pertuzumab. TPIV100 is a type of vaccine made from HER2 peptide that may help the body build an effective immune response to kill tumor cells that express HER2. Sargramostim increases the number of white blood cells in the body following chemotherapy for certain types of cancer and is used to alert the immune system. It is not yet known if TPIV100 and sargramostim will work better in treating patients with HER2 positive, stage II-III breast cancer. Read Less
