COVID-19 Clinical Trials and Expanded Access

This study is a randomized, double-blinded, and placebo controlled phase Ⅰ/Ⅱ clinical trial of the SARS-CoV-2 inactivated vaccine manufactured by Sinovac Research & Development Co., Ltd. The purpose of this study is to evaluate the safety and immunogenicity of the experimental vaccine in healthy adults aged 18~59 Years.

ACEI-COVID-19 is a multicenter, randomized trial testing the hypothesis that stopping/replacing chronic treatment with ACE-inhibitors (ACEI) or angiotensin receptor blockers (ARB) improves outcomes in symptomatic SARS-CoV2-infected patients

Given the current lack of effective COVID-19 treatment, it is necessary to explore alternative methods to contain the spread of the infection, focusing in particular on its mode of transmission. The modes of person-to-person transmission of SARS-CoV-2 are direct transmission, such as sneezing, coughing, transmission through inhalation of small droplets, and transmission through contact, such as contact with nasal, oral and eye mucous membranes. SARS-CoV-2 can also be transmitted directly or indirectly through saliva. The use of antiviral mouthrinses may be used as adjunctive therapy.

The current outbreak of COVID-19 pandemic has been marked by severe psychological problems. People around the world experienced a similarly frightening public health emergency, on a global scale, with the spread of this corona infection. (1) Studies of the Severe Acute Respiratory Syndrome (SARS) outbreaks that occurred in Canada, Taiwan, and Hong Kong found that the enormous emotional burden carried by those health care workers who were on the front lines of the battle against the disease led to psychological morbidity like anxiety, stress and even further leads to Post traumatic stress disorder. The initial phase of the COVID-19 outbreak in China in 2020 also reported more than half of the respondents rated the psychological impact as moderate-to-severe, and about one-third reported moderate-to-severe anxiety in general population.(2) - The chances of Fear, anxiety and stress are even higher in Individuals with preexisting liver disease as they have restriction of services for getting treatment. Moreover, they can have the following additional issues: - Fear of severe form of Corona present (as presented in most of the media and research) - Fear of dying - Added uncertainty - Family members also worried

In the context of quarantine with COVID-19, we will study the experience and psychological impact of pain in adult patients living with chronic pain. We will evaluate the link between the question of physical and psychological confinement in the experience of pain in this particular situation

This study will be conducted as a registry to identify asymptomatic or symptomatic persons to determine whether they carry SARS-CoV-2 antibodies.

The number of confirmed cases of COVID-19 infectious disease arising from the SARS-CoV-2 coronavirus is rising substantially and rapidly, with the potential to overwhelm the ability of the entire National Health Service (NHS) to cope with the increased demand. The availability of personal protective equipment is limited and reports of high risk procedures such as aerosol generating procedures (e.g. intubation for the sickest patients) is a source of great concern for infection transmission. Frontline NHS staff with direct patient contact have the highest likelihood of exposure to SARS-CoV-2 and development of COVID-19 disease. Efforts to protect these workers from development of COVID-19, using drugs to prevent the disease, require urgent evaluation.

According to recent publications, the percentage of caregivers infected with COVID 19 is evaluated between 10 and 30% . This great variability is due, on the one hand to the intensity of the influx of covid plus patients and, on the other hand, to the disparity in the preparation of caregivers in the face of this emergency. Indeed, we can understand that the strict application of hygiene rules can be faulted in the face of the volume of patients, the lack of protective equipment and the lack of specific training for caregivers in this area. As a result, within healthcare teams, there are many questions that generate anxiety: will I be able to provide care properly while protecting myself from the risk of contamination? This anxiety is also present and sometimes manifests itself aggressively in the entourage or in the vicinity of caregivers, due to lack of scientific data adapted to the local ecology of the crisis. Thus, the aim of this study is to show that the risk for caregivers of being contaminated by COVID in an area dedicated to COVID positive patients is no higher than being a caregiver in a non-COVID area that he either in the adult or pediatric sector.

The investigators want to study how the exposure to the covid-19 pandemic affects attitudes towards science and vaccination, and how other general attitudes and values are affected.

The rationale of the present clinical trial is that an orally available drug given to outpatients that could reduce the viral burden in the upper respiratory tract could forestall complications of SARS-CoV-2 infection and reduce transmission from one infected individual to another.
