The novel coronavirus (SARS-CoV-2) infection (COVID-19) has caused a worldwide pandemic. There is still much that is unknown regarding the virus, especially its effects on pregnancy, the fetus, and the neonate. This study seeks to evaluate adverse pregnancy and neonatal outcomes related to COVID-19 infection. The FDA has authorized emergency use authorization for the SARS-CoV-2 messenger ribonucleic acid (mRNA) vaccines from Pfizer and Moderna. Pregnant women were excluded from the Phase III clinical trials of the mRNA vaccines. There are no studies that have evaluated functional antibody responses, antibody reactivity to variant viruses, T cell frequencies or activity, or protection against infection or development of COVID-19. Having a more detailed understanding of how pregnancy and lactation alters the longevity, specificity, and activity of antiviral antibody and T cell-mediated immune responses to COVID-19 mRNA vaccines is essential for the FDA to inform future recommendations and regulation of these vaccines.

Background: The COVID-19 global pandemic killed more than 6 million people worldwide. Several vaccines have been developed against the virus that causes this disease. These vaccines are effective at preventing severe symptoms and death from COVID-19. Some people with chronic liver disease, especially those with an advanced condition called cirrhosis, do not respond to many vaccines as well as healthy people do. The goal of this natural history study is to find out how well people with chronic liver disease respond to the COVID-19 vaccines. Objective: To learn how chronic liver disease affects the body s immune response to vaccination against COVID-19. Eligibility: People aged 18 years or older with chronic liver disease. They must also be enrolled in protocol 91-DK-0214 or 18-DK-0091. Design: Participants will have 3 visits, each spaced 6 months apart. Each visit will last 2 hours. Participants will have their vital signs recorded. These include age, sex, race, height, and weight. They will give their medical history. At each visit, participants will have blood drawn through a needle inserted into a vein in the arm. The sample drawn at each visit will be from 1 to 8 tablespoons. At each visit, participants will fill out a questionnaire. They will answer questions about whether they have been vaccinated against COVID-19; whether they have had COVID-19; and whether they have been exposed to someone who had COVID-19. The questionnaire will take 10 to 15 minutes. Researchers will also look at results of past blood tests from other research studies.

Study VBT00001 is planned to be a Phase 1/2, randomized, modified double-blind, active-controlled, multi-center study to be conducted in approximately 980 adults aged 50 years and older in the United States. The purpose of the study is to assess the safety and immunogenicity of IIV-HD (high-dose inactivated influenza vaccine) + rC19 (adjuvanted recombinant COVID-19 vaccine) vaccine comprised of IIV-HD combined with different recombinant Spike (rS) antigen levels of rC19 compared to IIV-HD alone, rC19 (dose 1) alone, and IIV-HD and rC19 (dose 1) (coadministered in opposite arms). Placebo will be coadministered in the IIV-HD alone, rC19 (dose 1) alone, and IIV-HD + rC19 study groups to control for the number of injections and to maintain observer-blinding. Thus, each participant will receive two injections at enrollment, one in each deltoid muscle. Study details include: - The study duration will be approximately 12 months - Study intervention will be administered via a single intramuscular (IM) injection into the right and left deltoid muscles on D01 - Dose escalation with sequential enrollment (sentinel cohort followed by main cohort for a given dose) - The visit frequency will be D01, D09 (telephone call), D30, D182 (telephone call), and D366 (telephone call) Number of Participants: Approximately 980 participants are expected to be randomized.

Respiratory tract infections (RTIs) are prevalence community diseases and is the third leading cause of death worldwide. Rapid diagnosis of RTIs is essential as it drives decision points such as treatment, disposition, and containment. According to recent CDC (The Centers for Disease Control and Prevention) updates, nasopharyngeal swabbing is the preferred method of specimen collection for most RTIs such as SARS-COV-2. This process is invasive and traumatizing for patients as it requires probing (20 seconds) of the posterior nasopharynx with swab applicator. In some cases, this procedure has resulted in pain and injury. Because of the invasive nature of the procedure, patients often refuse testing or withdraw during the collection process resulting in inadequate specimen procurement. The study principle investigators (PI) have developed 2 novel specimen collection devices: 1) nasopharyngeal wash collection device (NP wash device) and 2) saliva collection device (the Oral Capsule). Both devices are designed for ease of use either by a healthcare professional or a patient. The benefits of such collection devices include 1) minimizing the invasive nature of the procedure because a swab applicator is not utilized and 2) minimizing infection risk to healthcare professional because the study devices can be self-administered when applicable. The study will enroll 1000 participants from a pool of patients presenting to the Nebraska Medicine Emergency Department (ED) who received a nasopharyngeal (NP) swab viral PCR test as part of their ED work up. Enrolled patients will be asked to provide four total specimens: 1) a saliva drool specimen, 2) a saliva Oral Capsule specimen, 3) a NP wash specimen, and 4) a finger stick serum specimen. Patients are able to opt out of any specimen collection method. Study specimens 1, 2, 3 will undergo a respiratory pathogen panel (RPP) PCR test and COVID-19 antibody testing. Study specimen 4 will undergo COVID-19 antibody testing and will function as a serum control for antibody detection.

Emerging data show that SARS-CoV-2 infection causes gut microbiome changes strongly associated with Post-Acute Sequelae of SARS-CoV-2 (PASC). The investigators and others have established that an orally ingested probiotic (Lactobacillus plantarum 299v, Lp299v) reduces circulating levels of cell-free mitochondrial DNA (cf-mtDNA), decreases toll-like receptor 9 (TLR9) activation [and downstream interleukin (IL-6)], and improves micro- and macrovascular (brachial artery) endothelial dysfunction [as measured by flow-mediated dilation (FMD%)] in humans. Recently published data also report impaired brachial FMD% and increased vascular stiffness post-SARS-CoV-2 infection. Based on these data, the investigators hypothesize that supplementation with Lp299v will attenuate SARS-CoV-2 associated endothelial dysfunction by reducing cf-mtDNA, TLR9 activation, and inflammation.

This study entitled Community-Centered Interventions for Improved Vaccine Uptake for COVID-19 (CIVIC): Getting to Yes, Michigan!, is designed to increase vaccine uptake among populations that experience COVID-19 related disparities. The investigators will focus on the four counties within Michigan where a disproportionate burden of COVID-19 is within African Americans and Latinx communities, i.e., Wayne, Genesee, Kent and Washtenaw Counties. Using a community-based participatory research (CBPR) approach, CIVIC will leverage: its long term relationships with the communities involved, an established CBPR Steering Committee developed and the knowledge gained as a Community Engagement Alliance (CEAL) grant recipient, the resources and networks of the University of Michigan CTSA (MICHR), and the expertise of our academic partners to identify and understand factors that contribute to COVID-19 vaccine hesitancy in African Americans and Latinx communities in Michigan. The investigators will develop and test interventions based on community-centered approaches to achieve a primary goal of increased vaccine uptake. The investigators will achieve this goal with the following aims: 1. Increase understanding of the barriers and drivers of vaccine uptake and hesitancy; 2. Increase vaccine uptake and decrease vaccine hesitancy through the implementation and evaluation of a multi-component intervention; and maintain, enhance, and evaluate the effectiveness of the CIVIC partnership to equitably engage all partners.

Thymalfasin (thymosin alpha 1 or Ta1), the active pharmaceutical ingredient in ZADAXIN® injection, is a 28-amino acid synthetic peptide, identical to natural Ta1 produced by the thymus gland. Ta1 is a biological response modifier which activates various cells of the immune system, and is therefore expected to have clinical benefits in disorders where immune responses are impaired or ineffective, including acute and chronic viral and bacterial infections, cancers, and vaccine non-responsiveness. Patients with end-stage renal disease (ESRD) on hemodialysis, in addition to their intrinsic kidney disease and frequent burden of comorbidities, also have increased risk of exposure to communicable diseases as they are treated several times each week at hemodialysis centers with several other patients and clinic staff in attendance. The majority of patients are over 60 years of age and many are receiving immunosuppressive medications. Accordingly, ESRD patients are particularly susceptible to COVID-19 infection. Ta1 has been shown to be safely administered to hemodialysis patients. It is our hypothesis that a course of Ta1 administered to individuals with ESRD will reduce the rate and severity of infection with COVID-19.

Mental health symptoms, including cognitive impairment ("brain fog"), following COVID-19 are of great concern to Veterans. This research seeks to advance understanding of the long-term effects of COVID-19 on neuropsychiatric and neurological functions, identifying clinically relevant biomarkers and directions for developing and testing therapeutic interventions. To accomplish these objectives the investigators are conducting a longitudinal study at two VA medical centers to: 1) assess and monitor cognitive function and psychiatric symptoms in Veterans post-COVID; 2) evaluate biomarkers of inflammation and signaling pathways associated with viral infection and neuropsychiatric function; and 3) integrate neuropsychiatric and neurological findings with biological data to identify biomarkers and clinical endpoints associated with disease progression or severity, as well as those for promoting brain repair and attenuating those symptoms.

The Long-Covid (LC)-Revitalize clinical study is testing repurposed drug treatments for Long Covid, involving adult participants from Brazil, Canada, Italy, Uganda, the United States, and Zambia. To qualify, participants must have had Covid-19 and experienced Long Covid symptoms for at least three months. The main goal of the study is to determine whether the drug treatments can improve symptoms in five key areas: 1) fatigue, 2) breathing, 3) memory, thinking, and communication, 4) muscle and joint pain, and 5) circulation. A secondary goal is to assess changes in the body, such as reducing inflammation, as well as to confirm the safety and tolerability of the treatments. In the first phase, 348 participants will take either one of two existing medications (upadacitinib or pirfenidone) or a placebo (a pill with no active ingredient) for three months. Although these medications are not yet approved for Long Covid, they are authorized for use in treating other health conditions. This study is adaptive, meaning it may adjust based on early results. In the second phase, the study could continue testing the most effective drug(s) against a placebo with new participants, explore combinations of drugs to see if they improve results, or discontinue the drugs if they prove ineffective or unsafe and test alternative treatments.

This is an appendix of master protocol (NCT05595369) designed to be flexible so that it is suitable for a wide range of settings within health care systems and in community settings where it can be integrated into COVID-19 programs and subsequent treatment plans. This sub-study is a prospective, multi-center, double-blind, randomized, controlled trial evaluating nirmatrelvir/ritonavir (Paxlovid) in two dosing durations for the treatment of Post-Acute Sequelae of SARS-CoV-2 Infection (PASC). The study is evaluating potential mechanisms of action, efficacy, and safety of antivirals and other therapeutics in individuals with PASC, according to the platform protocol objectives. The hypothesis is that persistent viral infection and/or overactive/chronic immune response and inflammation are underlying contributors to PASC and that antiviral and other applicable therapies may result in viral clearance or decreased inflammation and improvement in PASC symptoms.
