Vaccines Treatment Options in New Orleans, LA

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

The purpose of this study is to assess immune response and safety of various potencies of an investigational chickenpox vaccine given to healthy children 12 to 15 months of age. Read Less

This study is a Phase III, randomized, single-blind, placebo-controlled, multi-center study to be conducted in healthy infants and toddlers which will be enrolled at approximately 6 months of age (Cohort 1) and approximately 12 months of age (Cohort 2). The primary objective of the study will be to assess non-inferiority of the RSV infant and toddler (RSVt) vaccine antibody response when administered concomitantly with routine pediatric vaccines at 6 months of age (Diphtheria and Tetanus Toxoids and Acellular Pertussis, Inactivated Poliovirus, Haemophilus b Conjugate and Hepatitis B Vaccine \[Vaxelis® or Pentacel® and Recombivax HB®\] Prevnar 20®, and RotaTeq®), and 12 months of age (M-M-R II, VARIVAX, and Prevnar 20 or per local country recommendations) compared to when administered non-concomitantly.

The purpose of this study is to learn about the safety and immune effects of a pneumococcal vaccine in adults. This vaccine can possibly provide protection against further pneumococcal disease. This study will happen in 3 stages: Stage 1 is seeking participants who are between 18 years to 49 years of age. The participants will receive 1 of 2 pneumococcal vaccine candidates (different formulations) or 20vPnC (Prevnar 20) as a single shot given into the upper arm muscle. Stage 2 will begin after participants have completed Stage 1, and a pneumococcal vaccine candidate has been decided. Stage 2 is seeking participants who are adults 50 years of age and older. The participants will receive the chosen pneumococcal vaccine candidate from Stage 1 or 20vPnC (Prevnar 20). The vaccines will be given as a single shot into the upper arm muscle. Stage 3 is seeking participants who are adults 50 years of age and older. The participants will receive the chosen pneumococcal vaccine candidate from Stage 1 or a licensed pneumococcal comparator vaccine. The vaccines will be given as a single shot into the upper arm muscle. Participants will take part in this study for about 6 months for Stage 1 and Stage 3, and 12 months for Stage 2. During this time participants will have from 2 to 4 clinic visits and 1 phone visit. At these clinic visits, participants will be asked if any side effects were experienced. The participants will also have to give blood samples during these clinic visits. 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 evaluate the safety and immunogenicity of a single intramuscular (IM) injection of different formulations of Quadrivalent Influenza Vaccine (QIV) messenger ribonucleic acid (mRNA) (MRT5421, MRT5424, and MRT5429) compared to an active control (QIV- standard dose (SD), QIV- high dose (HD) \[adults ≥ 65 years of age only\], or quadrivalent recombinant influenza vaccine (RIV4)) in adults 18 years of age and older.

The objective of the study is to evaluate the safety and tolerability of a single injection of VAX-24 at 3 dose levels compared to Prevnar 20™ (PCV20) in adults 65 years of age and older. Read Less

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. Read Less

The purpose of this study was to demonstrate the non-inferior HAI immune response of quadrivalent recombinant influenza vaccine (RIV4) vs licensed Egg-Based Quadrivalent Influenza Vaccine (IIV4) for the 4 strains based on the egg-derived antigen in all participants aged 3 to 8 years and to describe the immunogenicity and safety profile of RIV4 compared to IIV4 in participants aged 3 to 8 years.

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.

The primary objectives of the study were: * To assess the safety profile of each dose of the study product after each and any administration in all infants and toddlers regardless of baseline serostatus. * To characterize the Respiratory Syncytial Virus (RSV) A serum neutralizing antibody responses to the study product in each vaccine group after vaccination in RSV-naïve participants. The secondary objectives of the study were: * To quantify the amount of vaccine virus shed by each participant by baseline serostatus. * To determine the proportion of vaccinated infants and toddlers in each vaccine group infected with the vaccine virus at D56 (56 days after vaccination 1) for Cohorts 1, 2, 3 and 4, and at Day 84 (28 days after vaccination 2) for Cohorts 2 and 4 by baseline serostatus. * To characterize the RSV A serum neutralizing antibody responses to the study product in each vaccine group after vaccination in RSV-experienced participants. * To characterize serum RSV anti-F immunoglobulin G (IgG) antibody responses to the study product in each vaccine group after vaccination by baseline serostatus. * To characterize serum RSV antibody responses (RSV A-neutralizing and anti-RSV F IgG) to the study product in each vaccine group after the RSV surveillance season or at least 5 months after the last vaccine administration by baseline serostatus.
