Vaccines Treatment Options in New Orleans, LA

The primary objective of this study is to determine the magnitude and breadth of the serum antibody response to the nonavalent HPV vaccine (Gardasil-9) in adults with well-controlled HIV infection. The secondary objectives of the study are to observe short term clinical outcomes of prevalent HPV genotype-specific anogenital infections in adults living with HIV who complete the three-dose Gardasil-9 vaccine series, and to determine the protection afforded by Gardasil vaccine over time in previously vaccinated adults living with HIV. The clinical hypothesis is that adults with virologically controlled HIV mount a serum antibody response to the nonavalent HPV vaccine that is comparable to HIV negative counterparts. We also postulate that HPV vaccination will provide short-term clinical benefit against HPV infections and disease associated with vaccine genotypes and continuing protection against vaccine genotypes of HPV over time.

The primary objective of the study is to determine the relative efficacy of the investigational oral severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) vaccine tablet VXA-CoV2-3.1 compared to a currently recommended vaccine for the prevention of symptomatic Coronavirus Disease 2019 (COVID-19).

This study will enroll individuals who have: * Completed primary series of mRNA COVID-19 vaccine, and * An antibody response ≤ 2500 U/mL measured at least 30 days after the last dose of vaccine. This group of patients is at high risk for severe COVID-19 disease due to pharmacologic immunosuppression and a high prevalence of non-transplant risk factors such as obesity and diabetes. Read Less

This study is a Phase 3, randomized, modified double-blind study which aims to measure whether the investigational pneumococcal conjugate vaccine PCV21 is safe and can help the body to develop germ-fighting agents called "antibodies" (immunogenicity) when it is given after 1 dose, 2 doses, or 3 doses of a licensed 20-valent pneumococcal vaccine compared to when 20-valent pneumococcal vaccine is given as a complete series in infants aged from approximately 2 months (42 to 89 days). The study duration per participant will be up to approximately 19 months. The study vaccines (either PCV21 or 20vPCV) will be administered at approximately 2, 4, 6 and 12 to 15 months of age (MoA). Routine pediatric vaccines will be given as per local recommendations. There will be 6 study visits: Visit (V)01, V02 separated from V01 by 60 days, V03 separated from V02 by 60 days, V04 separated from V03 by 30 days, V05 at 12 months of age until 15 months of age, V06 separated from V05 by 30 days.

To assess the ability of RSVPreF3 OA investigational vaccine to generate an immune response when given in combination with HZ/su vaccine and its safety in older adults, aged \>=50 years of age. Read Less

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

This purpose of this phase 3 multicenter, parallel-group, open-label study is to learn about the safety, tolerability, and immunogenicity of RSVpreF and HZ/su vaccine when given together in adults 50 years of age and older. 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

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
