This study is to learn about flu and COVID vaccines, either alone or when mixed together. Healthy people aged 18 or older can join. Participants will get one shot in each arm, either a flu or COVID vaccine, alone or mixed. The study lasts about 6 months, and participants need to visit the research site at least 3 times.

The purpose of this study is to measure the safety and the immune response to 3 next-generation influenza vaccine candidates (mRNA-1011.1, mRNA-1011.2, and mRNA-1012.1) compared with influenza vaccine candidate mRNA-1010 controls in healthy adult participants. Read Less

The study is divided into 2 parts: Part 1 and Part 2. The purpose of Part 1 of this study is to generate sufficient safety, reactogenicity, and immunogenicity data to enable selection of an mRNA-1083 vaccine composition and dose level to evaluate in a subsequent Phase 3 clinical trial in adults. The purpose of Part 2 of this study is to generate safety and immunogenicity data for additional mRNA-1083 compositions and dose levels in young adults ≥18 years and \<50 years of age. Read Less

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. Read Less

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 phase 3, randomized, double-blind, active comparator-controlled study of the safety, tolerability, and immunogenicity of V116 compared to PCV20 (pneumococcal 20-valent conjugate vaccine (\[Prevnar 20™ / APEXXNAR™\]) in pneumococcal vaccine-naïve adults. It is hypothesized that V116 is noninferior to PCV20 for the common serotypes and superior to PCV20 for the unique serotypes as assessed by serotype specific opsonophagocytic activity (OPA) 30 days postvaccination. It is also hypothesized that V116 in participants 18 to 49 years of age immunobridges to V116 in participants 50 to 64 years of age as assessed by serotype specific OPA geometric mean titers (GMTs) 30 days postvaccination for all 21 serotypes in V116. Participants ≥50 years of age will be enrolled in Cohort 1, and participants 18 to 49 years of age will be enrolled in Cohort 2. Read Less

Primary Objectives: * Assessed the immune response of the 3 SP0202 formulations, Prevnar 13 and Pneumovax 23 30 days after the administration of the single dose vaccination * Assessed the safety profile of the 3 SP0202 formulations, Prevnar 13 and Pneumovax 23 Read Less

This is a Phase 2/3 open-label study to evaluate the safety and immunogenicity of a booster dose of the XBB.1.5 severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) recombinant (r) spike (S) protein nanoparticle vaccine (SARS-CoV-2 rS) adjuvanted with Matrix-M™ in previously mRNA COVID-19 vaccinated adult participants ≥18 years of age and baseline SARS CoV-2 seropositive COVID-19 vaccine naïve participants ≥18 years of age.

This study was designed to evaluate the safety and tolerability of a single dose of V114 when administered concomitantly and non-concomitantly (i.e., 30 days after) with influenza vaccine. It also evaluated whether V114 can be administered concomitantly with influenza vaccine without impairing the antibody response to the 15 serotypes contained in V114 and to the 4 influenza viruses contained in the seasonal inactivated quadrivalent influenza vaccine (QIV). The primary hypotheses state that immune responses to V114 and to QIV are non-inferior when administered concomitantly as compared with non-concomitant administration as measured by serotype-specific opsonophagocytic activity (OPA) and hemagglutination inhibition (HAI) geometric mean titers (GMTs) at 30 days postvaccination. This study will also contribute to the overall safety database and immunogenicity data for V114 to support initial licensure in adults. Read Less

This phase 2B, placebo-controlled, randomized, observer-blinded trial will evaluate the safety, tolerability, and immunogenicity of the investigational multivalent group B streptococcus vaccine administered concomitantly with Tdap in healthy nonpregnant women 18 through 49 years of age. Read Less

This multicenter, randomized, open-label study will evaluate the immune response to vaccines (tetanus toxoid \[TT\]-containing adsorbed vaccine, 23-valent pneumococcal polysaccharide vaccine \[23-PPV\] either unboosted or boosted with 13-valent pneumococcal conjugate vaccine \[13-PCV\], influenza vaccine, keyhole limpet hemocyanin \[KLH\]) after administration of a dose of ocrelizumab (OCR) in participants with relapsing multiple sclerosis (RMS).
