Vaccines Treatment Options in Maryland

Background: Epstein-Barr virus (EBV) is the primary cause of infectious mononucleosis, commonly known as mono. EBV infects more than 90% of the world s population. Mono can be serious, and it can lead to severe illnesses like cancer and autoimmune diseases. Researchers want to test vaccines that may help prevent EBV and associated diseases. Objective: To test two EBV vaccines: EBV gH/gL/gp42-ferritin and EBV gp350-ferritin. Eligibility: Healthy EBV-negative or EBV-positive people aged 18 to 29. Design: Participants will be screened. They will have a physical examination. They will give blood and saliva samples. They will receive 3 doses of the study vaccine as an injection in the shoulder muscle. They will get either one vaccine or a combination of both vaccines. Participants will get their first dose of the vaccine at visit 1, the second dose about 30 days later, and the final dose about 90 days after that. Participants will be given a memory aid so they can record any symptoms and side effects between visits. This can be done either on paper or online through a link that is emailed to them. There are 6 required in-person visits. There are also 2 optional visits. In between the in-person visits are 7 telehealth visits or phone calls. Each visit may take up to 4 hours. The study will last for about 17 months. Participants will have the option of staying in the study for an additional year. 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

This study is a Phase 3, randomized, modified double-blind study which aims to document the safety profile of the PCV21 vaccine (investigational pneumococcal vaccine) compared to a licensed 20-valent pneumococcal conjugate vaccine 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. 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.

This phase II trial studies the effect of DNA plasmid based vaccine (STEMVAC) in treating patients with patients with stage IB-III triple negative breast cancer. STEMVAC may wake up the immune system in patients who have had a diagnosis of triple negative breast cancer and have been treated. STEMVAC targets proteins that are expressed on breast cancer cells and works by boosting the immune system to recognize and destroy the invader cancer cell proteins that are causing the disease. The purpose of this trial is to test the immune system's response to STEMVAC. Read Less

Conducting an initial small, controlled clinical pharmacology trial to assess for therapeutic biologics activity (proof-of-concept) that suggests the potential for clinical benefit of COVID-19 patients with controlled cancers. 1. Treat Infection of Multiple Gene Mutation COVID-19 Virus Strains. 2. Activate Human Antigen Presentation Reaction to COVID-19 Specific Antigen. 3. The human antigen presenting cells (APCs) can take up and process COVID-19 target antigen protein into small peptide fragments, and then COVID-19 virus can be killed by APCs directly. Read Less

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-CoV2-3.3 compared to a currently recommended vaccine for the prevention of symptomatic Coronavirus Disease 2019 (COVID-19). In order to represent a more recently circulating SARS-CoV-2 variant, the main study endpoints will now evaluate the VXA-CoV2-3.3 (KP.2 strain) vaccine, and not the VXA-CoV2-3.1 (XBB.1.5 strain) vaccine.

The purpose of this study is to evaluate the immunogenicity, safety, and reactogenicity of mRNA-1083 as compared with active control, co-administered licensed influenza and severe acute respiratory syndrome coronavirus 2 (SARS CoV 2) vaccines, in 2 independent age-group sub-study cohorts, healthy adults 65 years and older (Cohort A) and healthy adults 50 to \<65 years of age (Cohort B).

The purpose of this study is to evaluate the immunogenicity and safety of Ad26.RSV.preF-based vaccine and quadrivalent high-dose seasonal influenza vaccine when administered either concomitantly or separately. Read Less

Purpose: To study the immune response of the newly licensed pneumococcal conjugate vaccine (PCV) in comparison to the pneumococcal polysaccharide vaccine (PPV) to determine if a significantly better immunologic response to boosting can be elicited in patients previously vaccinated with PPV.

This is a trial to evaluate the safety and immunogenicity of double mutant heat-labile toxin LTR192G/L211A (dmLT) from Enterotoxigenic Escherichia coli (ETEC) by oral, sublingual, or intradermal vaccination in approximately 135 healthy adult volunteers, age 18-45 years. Study duration is approximately 2.5 years, with each participant duration for up to 9 months depending on the route of dmLT administered. There is no specific hypothesis being tested in this study. The primary objective of this study is to assess the reactogenicity, safety, and tolerability of dmLT when administered in three sequential doses, over a range of dosages by oral, sublingual, or intradermal routes.

The aim of this study is to evaluate the safety and immunogenicity of a human metapneumovirus (hMPV) / respiratory syncytial virus (RSV) mRNA vaccine candidate encapsulated in a lipid nanoparticle (LNP) based formulation (hereafter referred to as hMPV/RSV vaccine) for the prevention of lower respiratory tract disease (LRTD) caused by hMPV and/or RSV among adults aged 60 years and older. Overall, the study is designed to address the following goals: * Assess the safety profile of the candidate formulations. * Describe the immunogenicity profile of the candidate formulations. * Select the vaccine formulations (dose) for future development. * Assess the safety and immunogenicity of a booster vaccination of the selected formulation administered 12 months after the primary vaccination in a subset of the study population. The study duration is as follows: -Six months each for the Sentinel and Main Cohorts; up to 12 months for the Expansion Cohort, and 12 additional months for the Booster Cohort Treatment duration: * Stage 1 Sentinel Cohort: 1 intra-muscular (IM) injection. Participants will be followed for 6 months post vaccination * Stage 1 Main Cohort: 1 IM injection. Participants will be followed for 6 months post vaccination * Stage 2 Expansion Cohort: 1 IM injection. Participants in the selected formulation arm, and participants in the Licensed RSV vaccine arm will be followed for 12 months post-vaccination; the remainder of the participants will be followed for 8 months post-vaccination * Stage 2 Booster Cohort: 1 IM injection 12 months post-primary vaccination. Participants will be followed for 12 months post-booster vaccination Read Less
