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 2/3, randomized, double-blind study to evaluate the safety and immunogenicity of different booster dose levels of the monovalent severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) recombinant (r) spike (S) protein nanoparticle (SARS-CoV-2 rS) vaccines with Matrix-M™ adjuvant (NVX-CoV2373 \[prototype Wuhan vaccine with Matrix-M adjuvant\] or NVX-CoV2601 \[Omicron XBB.1.5 subvariant vaccine with Matrix-M adjuvant\]).

This study is a large-scale investigation (Phase 3) into a new booster shot designed specifically for teenagers. The booster targets a particular variant of COVID-19, Omicron XBB.1.5. The main focus is on safety: researchers want to see if this new booster is safe for teenagers who have already received two doses of the Pfizer or Moderna mRNA COVID-19 vaccines. To ensure a fair comparison, the study will use a double-blind approach. This means two groups of teenagers will receive booster shots, but neither the teenagers nor the researchers giving the shots will know beforehand which version of the booster each person gets. The study will also assess how well the body fights the virus after the booster shot. Read Less

This is a phase 1 clinical trial to evaluate the safety, tolerability, and immunogenicity of HIV-1 envelope protein BG505 SOSIP.GT1.1 gp140 trimer Vaccine, Adjuvanted, in up to 48 healthy HIV-uninfected adult volunteers. Read Less

An antibody is a substance your body makes to fight off infection. This study will explore the safety and antibody response of a vaccine to prevent severe diarrhea caused by a germ called Clostridoides difficile (C. diff). Three new formulations of the C. diff vaccine will be used in this study, in addition to a C. diff vaccine formulation that has been studied in previous clinical trials. The purpose of this study is to understand if giving the new C. diff vaccine formulations helps people make as many antibodies as giving the previously studied C. diff vaccine formulation. The study is divided into 2 phases. Phase 1 will evaluate 3 new formulations of the C. diff vaccine and 2 dosing schedules spread out over 2 months or 6 months. The Phase 1 portion of the study is seeking participants: * who are healthy adults of 65 to 84 years of age * who have not had a C. diff infection before * who have not received a C. diff vaccine or C. diff monoclonal antibody therapy before. All participants in Phase 1 will receive study injections with active vaccine or placebo at each vaccination visit, depending on the vaccine group to which they are assigned. A placebo does not contain any active ingredients. Participants in Phase 1 will attend at least 9 study visits and will take part in the study for approximately 18 months. Based on the results of Phase 1, 1 or 2 of the new C. diff vaccine formulations will be chosen for further study in Phase 2. Phase 2 will evaluate the safety and effects of the new C. diff vaccine formulation(s) chosen in Phase 1. The Phase 2 portion of the study is seeking participants: * who are healthy adults ≥65 years of age * who have not had a C. diff infection before * who have not received a C. diff vaccine or C. diff monoclonal antibody therapy before. Phase 2 participants will receive active C. diff vaccine or placebo at each vaccination visit. Participants in Phase 2 will attend at least 6 and up to 12 study visits and will take part in the study for up to 4 years. 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

The purpose of this Phase III study is to assess the efficacy, safety, and immunogenicity of two CoV2 preS dTM-AS03 vaccines (monovalent and bivalent) as part of primary series vaccinations in a multi-stage approach, as well as a booster injection of a CoV2 preS dTM-AS03 vaccine, in adults 18 years of age and older. A total of approximately 21 046 participants are planned to be enrolled (5080 per study intervention group in Stage 1 and 5443 per study intervention group in Stage 2). Initial, double-blind, primary series study design is planned for 365 days post-last Initial injection (ie, approximately 386 days total) for each participant. Based on decisions of the Study Oversight Group, Stage 1 and Stage 2 participants will be invited to participate in an unblinded Crossover / Booster study design with duration as follows: * For participants who initially received vaccine: 12 months post-booster (ie, approximately 18 to 24 months) * For participants who initially received placebo: ≥ 4 months post-last dose of the primary series + 12 months post-booster (ie, approximately 28 to 34 months) * For participants who do not consent to continue in the unblinded Crossover / Booster part of the study, all study procedures will be stopped and participants will be discontinued from the study.
