Filter by:SARS CoV-2 is the virus responsible for the pandemic COVID-19, which has resulted in nearly five million deaths worldwide since its spread in the beginning of 2020. In the United States, there are now two emergency use authorized vaccines that make use of messenger ribonucleic acid (mRNA) based technology that are highly effective for preventing COVID. However, because multiple sclerosis is an autoimmune condition, many individuals with multiple sclerosis take medicines that affect the immune system. The investigators are not sure whether individuals on certain MS medications, including medications that lower a type of immune cell called B lymphocytes, will form as robust of a response to the vaccines. In this study, the investigators will be gathering more information about effectiveness of these vaccines and bloodwork that looks at antibodies and other markers of vaccine response and by asking patients about COVID-19 infections.
This study is a double-blind, randomized phase Ⅳ clinical trial of the inactivated SARS-CoV-2 vaccine (CoronaVac)manufactured by Sinovac Research & Development Co., Ltd. The purpose of this study is to evaluate the lot-to-lot consistency ,immunogenicity and safety of COVID-19 vaccine between the commercialized scale in workshop 2 and 3 and the commercialized scale in workshop 1 in healthy children aged 3-17 years.
This project will address key testing challenges in Utah schools by building on collaborations with public school districts, private schools, charter schools and with Utah Department of Health on coronavirus disease (COVID-19) testing and existing infrastructure. The study team will work closely with schools and the Utah public health system to implement and test a shovel-ready and scalable health information technology approach that delivers automated text messages (TM) to students' parents and faculty/staff members around COVID-19 testing. In addition, some students and faculty/staff will receive a health navigator (HN) follow-up to ensure that tests are completed. Families (both of students and faculty/staff members) will be offered the recently FDA-approved in-home serial testing approach if accessing in-person testing is a challenge. While this project is focused on COVID-19 testing, in the case that the COVID-19 vaccination becomes more relevant or is the priority of the school, the study team is able to tailor the intervention to focus on the vaccine as well. The outcomes in this study utilized parent/student reported data. Staff data were also collected but will not be reflected in primary outcome analyses.
A multicenter, randomized, double-blinded, placebo-controlled, phase 3 clinical efficacy study evaluating nitric oxide nasal spray (NONS) as prevention for treatment of individuals at risk of exposure to COVID-19 infection.
Great expectations to control the pandemic are placed in vaccines against COVID-19. Currently, the four COVID-19 vaccines approved in the European Union. We have designed the study assessing the anti-SARS-CoV-2 IgG antibody titer after vaccination cycle the BNT162b2 vaccine in several time points relating these results to the COVID-19 history and severity of symptoms during the disease and after the first and second vaccine dose
This study investigates patients' perceptions of their doctor's or nurse's empathy during an in-person interaction with the doctor or nurse wearing personal protective equipment (PPE) compared to during a video interaction with the doctor or nurse without PPE. The goal of this research study is to learn whether patients who visit the Acute Cancer Care Center at MD Anderson believe they get better (more empathetic) care from doctors who visit them in person wearing PPE or from doctors who visit them by video call and do not wear PPE.
A Global, Multi-center, Randomized, Double-Blind, Placebo-Controlled, Phase III Clinical Study to Evaluate the Efficacy, Safety, and Immunogenicity of Recombinant SARS-CoV-2 Fusion Protein Vaccine (V-01) in Adults Aged 18 Years and Older
InVITE is funded by NIAID and is conducted in multiple international sites (approximately 20 sites across 7 countries). This is a study of adults who receive locally available COVID-19 vaccines through local vaccination programs. Persons will be enrolled within one day (before or after) of receipt of a COVID-19 vaccine. The study will enroll participants who receive COVID-19 vaccination at local clinics and/or study sites.
It is a prospective open-labeled study, We intended to recruit the participants who completed 2 doses of inactivated COVID-19 vaccine 4-8 months before, and volunteered to receive the third dose of vaccine (inactivated vaccine, recombinant subunit protein vaccine or mRNA vaccine) into the experimental group, and the participants who completed 2 doses of inactivated COVID-19 vaccine 4-8 months before without a third dose of vaccination plan into the control group. Participants in the experimental group received the third dose of SARS-CoV-2 vaccination at baseline, and participants in the control group received no intervention. Each subject will be followed up for one year after enrollment, and neutralizing antibodies and total antibodies will be tested at the specified time points, as well as the records of adverse events and adverse reactions.
Covid-19 has the potential to affect physical, cognitive and psychological functions in multiple ways. It has been clear that a significant proportion of patients with Covid-19 develop long-term symptoms. The term post-acute Covid-19 syndrome (PACS) is now used to describe the wide range of prolonged symptoms following the infection. Patients may need specialized rehabilitation to be able to meet the complex symptoms and problems that may arise. A more specific syndrome that seems to occur more frequently than expected in the group of non-hospitalized patients who have had Covid-19 is the postural orthostatic tachycardia syndrome (POTS). To evaluate the effects of physical training in patients with POTS after Covid-19 a single subject design will be used (the patient is their own control). Inidividual semistructured interviews will be performed to explore and describe the patients´ experiences of the rehabilitation intervention. Participants: Patients diagnosed with POTS after Covid-19 (N=30) will be included. Procedure and outcomes: The primary outcomes are physical activity and health-related quality of life. Secondary outcomes are: physical capacity, active standing test, Malmö-POTS-questionnaire, Anxiety and depression, fatigue, self-reported outcome measure of physical function and work ability. Initially measurements will be performed several times during a period of 2-4 weeks to obtain a baseline before the intervention starts. Then the included participants will undergo a specially designed physical training program that will be performed 3 times /week during a period of 12 weeks. The intervention of physical training will consist of different exercises to enhance muscle strength and endurance. The intervention will be individually adjusted with a progression in dose, intensity, and position. The exercise is based on a program used in a previous study. Measurements will then be repeated after completion of the intervention period. A qualitative approach, with semistructured interviews, will be used to explore the patients´ experiences of the intervention, after commence of the interventional trial.
