Active clinical trials for "COVID-19"

the aim of the current study is to compare the effect of conventional facial PPE as 1)goggles + surgical masks, and 2)face shields + surgical masks versus 3)half-face and 4)full-face reusable respirators; on preoperative child's fear in the dental office.

To evaluate the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD), and immunogenicity of AZD7442 in Healthy Chinese Adults. vs. placebo

This is a study trial to assess the effectiveness of the immune response stimulated by the genetically engineered Bacillus subtilis which express and display Spike protein of the SARS-COV2 on the spore coat.

To evaluate the safety and tolerability of a single dose of 600 mg AZD7442 administered IV (intravenous) to Chinese adults (including those with stable medical conditions).

The study was conducted experimentally to evaluate the effect of neurolinguistic programming on COVID-19 fear in kidney transplant patients.

The COSI BAIR trial will involve approximately 60 children, aged 5 to 8 years old, comprising a subset of participants from the Melbourne Infant Study BCG for Allergy and Infection Reduction (MIS BAIR) randomised controlled trial. The overall aim of this trial is to investigate the specific and heterologous effects of COVID-19 vaccination on immunity in children. COSI BAIR will aim to recruit its participants from the MIS BAIR Bacillus Calmette-Guérin (BCG)-naïve group. These children will be followed up until 28 days after their final Coronavirus Disease 2019 (COVID-19) vaccination. Venous blood samples will be collected at two study visits, at Murdoch Children's Research Institute (MCRI): Day 0 - baseline (day of COVID-19 vaccination #1), and Day 84 (28 days after COVID-19 vaccination #2).

The immunomodulatory effects of vitamin D are known to be beneficial in viral infections, it is also known that its deficiency is associated with a worse prognosis of COVID-19. This study aimed to determine the baseline vitamin D serum concentrations in asymptomatic or mildly symptomatic COVID-19 outpatients, as well as to evaluate the effects of supplementation with 10,00 IU/daily of vitamin D3 and its relationship with biochemical parameters and clinical features.

The immune system response needs to be forceful but also balanced for a rapid recovery from infection which avoids harmful overreactions. Innate immunity can adapt and respond more efficiently to secondary exposures, thanks to epigenetic and metabolic reprogramming, namely "trained immunity". ABBC1 is a combination of beta-1,3/1,6-glucan with inactivated Saccharomyces cerevisae rich in selenium and zinc for training immunity. ABBC1 includes repurposed synergistic yeast-based ingredients: a unique ß-1,3/1,6-glucan complex and a consortium of probiotic Saccharomyces cerevisiae, rich in Selenium and Zinc. ABBC1 induces trained immunity due to its specific chemical and tridimensional structure: its ß-glucan complex interacts with specific receptors in immune cells, provoking a release of cytokines and priming phagocytosis. Simultaneous activation of these pathways activates innate immunity and counteracts cytokine storm. ABBC1 provides highly bioavailable selenium and zinc, micronutrients with a critical role in an optimal immune responsiveness to allergy, infection, and vaccines. ABBC1 possesses proven microbiome modulating properties, which revert in immune training. Due to its high tolerance, safety and immediate availability, ABBC1 is an ideal candidate for complementary management of geriatric patients with seasonal influenza viruses or COVID-19, or to improve the immune response in the general population receiving the influenza or Covid-19 vaccines. The absence of drug interactions in ABBC1 allows a dosage that is fully compatible with the medication prescribed for all types of patients, including the elderly who are frequently polymedicated, and allows adding an additional therapeutic tool in the fight against the pandemic. This study assesses the benefits of a nutritional supplementation with ABBC1 in volunteers receiving the influenza vaccine during autumn 2020 and the Covid-10 vaccine during winter 2021.

This is a Phase 1 Randomized, Double-Blind, Parallel Group, Placebo-Controlled Study to Assess the Safety of Ascending Doses of UNI911 INHALATION in Healthy Volunteers in Preparation for Evaluation in Adults with COVID-19

The purpose of this study is to document the feasibility and tolerability of low dose thoracic radiotherapy in patients with WHO level 5 COVID 19 infections.
