Filter by:The objective of this study is to evaluate the efficacy, immunogenicity and safety of two different strengths (3 µg/0.5 mL and 4,5 µg/0.5 mL) of inactivated COVID 19 Vaccine- TURKOVAC in healthy subjects following 3rd vaccination to demonstrate clinical evidence in prophylaxis of COVID 19.
The aim of the project is to study the feasibility of implementing a novel point-of-care test (POCT) for rapid detection of SARS-CoV-2 infection. A CRISPR-based detection kit would be piloted for testing of suspected SARS-CoV-2 infection in healthcare setting, with the objectives of evaluating the performance of the new test in the detection of SARS-CoV-2, and assessing the practicability of the new test for diagnosing SARS-CoV-2 infection in healthcare settings.
Coronavirus disease 2019 (COVID-19) is a respiratory disease caused by a novel coronavirus, which has developed the global pandemic situation. The promotion of vaccination is an effective strategy to control the epidemic. A total of 19,5738,000 doses of COVID-19 vaccines have been reported in China until August 24th, 2021. During widespread vaccination, the education in COVID-19 prevention and vaccination for residents are also crucial. To figure out the influence of education during waiting time of vaccination, we have designed a randomized controlled trial and planned to distribute leaflets and questionnaires to the residents of Xidian (a town in Ninghai, Zhejiang). This study is of great significance for the prevention of COVID-19 pandemic.
This is randomized, blinded and controlled design. Among the randomly selected subjects who have been vaccinated with two doses of Inactivated COVID-19 vaccine (Vero cell), based on a step-wise approach, the subjects will receive one dose of recombinant COVID-19 vaccine sequentially at different shedules of 1-3 months, 3-6 months and ≥ 6 months after two doses of vaccination, and the subjects vaccinated at different schedules will be randomly assigned to different sequential immunization groups. At the same time, each sequential immunization group will be matched with a control group with the inactivated COVID-19 vaccine (vero cells) as the booster dose.
Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), was first identified in Wuhan, China. It rapidly spread, resulting a global pandemic in March 2020. Globally, till 27 August 2021, there have been 214,468,601 confirmed cases of COVID-19, including 4,470,969 deaths, reported to WHO. With the absence of curative treatment for COVID-19 infection the development of safe and effective vaccines is critical to ending the COVID-19 pandemic. The Pfizer/BioNtech Comirnaty vaccine was listed for WHO Emergency Use Listing (EUL) on 31 December 2020. The SII/Covishield and AstraZeneca/AZD1222 vaccines (developed by AstraZeneca/Oxford and manufactured by the State Institute of India and SK Bio respectively) were given EUL on 16 February. The Janssen/Ad26.COV 2.S developed by Johnson & Johnson, was listed for EUL on 12 March 2021. The Moderna COVID-19 vaccine (mRNA 1273) was listed for EUL on 30 April 2021 and the Sinopharm COVID-19 vaccine was listed for EUL on 7 May 2021. The Sinopharm vaccine is produced by Beijing Bio-Institute of Biological Products Co Ltd, subsidiary of China National Biotec Group (CNBG). The Sinovac-CoronaVac was listed for EUL on 1 June 2021. As of 25 August 2021, a total of 4,953,887,422 vaccine doses have been administered. In large, randomized-controlled trials, vaccines were found to be safe and efficacious in preventing symptomatic, laboratory-confirmed COVID-19. However, a small percentage of fully vaccinated persons will develop symptomatic or asymptomatic infections with SARS-CoV-2, the virus that causes COVID-19. A vaccine breakthrough infection is defined as the detection of SARS-CoV-2 RNA or antigen in a respiratory specimen collected from a person ≥14 days after receipt of all recommended doses of an FDA-authorized COVID-19 vaccine. A total of 10,262 SARS-CoV-2 vaccine breakthrough infections had been reported from 46 U.S. states and territories as of April 30, 2021. Among these cases, 6,446 (63%) occurred in females, and the median patient age was 58 years (interquartile range = 40-74 years). Based on preliminary data, 2,725 (27%) vaccine breakthrough infections were asymptomatic, 995 (10%) patients were known to be hospitalized, and 160 (2%) patients died.
Multiple Sclerosis (MS) is a demyelinating auto immune disease of the central nervous system, affecting 2500000 people worldwide. Risk factors for MS severity are not yet well-known , but previous studies highlighted that relapse rate increased during influenzae epidemics, and air pollution could be a risk factor for MS relapses. MS is a neurological chronic disease that requires constant medical treatment and regular rehabilitation care. COVID-19 pandemic and restrictive measures taken to limit contaminations have drastically decreased air pollution and seasonal viral infections exposure, but sanitary crisis also limited care access for MS patients (medical treatment, rehabilitation). Therefore, this particular period offers a unique opportunity to evaluate the impact of air pollution, viral infections, and health care access on the severity of MS. The main objective is to evaluate the impact of air pollution and seasonal viral infections on the risk of MS relapse, using the year 2020 as a quasi-experimental model. The secondary objective will be to evaluate the impact of health care access limitations on the risk of neurological disability accumulation. This study will include 1500 MS patients, living in Ile de France, followed in the neurological department of "Pitié-Salpêtrière" Hospital. This is a retrospective observational study nested in OFSEP registry (French Multiple Sclerosis Observatory), which is a prospective cohort of MS patients in France. Air pollution data will come from AIRPARIF, and viral infections data will come from "Santé Publique France". A better knowledge of the impact of air pollution, viral infections, and health care access on the course of MS will enable to better guide information to patients and public health care decisions.
The coronavirus SARS-CoV-2 causing COVID-19 was pandemic since 2020. Vaccination is one of the most important measure to control the outbreak. The countries of the world started the vaccination since December, 2020. Taiwan started since March, 21st, 2021. Currently, Taiwanese people receive COVID-19 vaccination by either AZ or Moderna; Pfizer/BNT vaccine may import in the near future. The side effects post vaccination including injection site pain, fatigue, headache, myalgia, chills, arthralgia, fever, and so on. Incidence of side effects more frequent in young people than elders; more frequent in the first dose than second dose in AZ vaccine; more frequent in the second dose in Moderna or Pfizer/BNT vaccine. Taiwan V-watch is a system monitored by CDC for people proactive notification of side effects post COVID-19 vaccination. But it doesn't include the objective cardiovascular parameters, for example, heart rate, arrhythmia, blood pressure, central body temperature (ear temperature) and blood oxygen saturation level. This study aims to monitor the physiologic and psychologic effects, and side effects before and after COVID-19 vaccination in patients at high cardiovascular risk, including hypertension, hyperlipidemia, and type 2 diabetes, and arrhythmia or coronary artery disease. The investigators arrange two weeks of continuous home BP/HR monitoring (7 days pre- and post-vaccination) for evaluation of physiologic effects post vaccination. Due to fever noted in some people post-vaccination, the investigators also measure ear temperature, pulse oximetry, and environmental temperature and humidity, for the reference of BP monitoring. In conclusion, this study may provide important information of cardiovascular response and psychosocial effects after SARS-CoV-2 vaccination for proactive prevention of cardiovascular complications.
The COVID-19 outbreak has been categorized as a pandemic and declared an international public health emergency by WHO. In this context, an exceptional mobilization and a complete reorganization of the organization of the healthcare offer was put in place.The investigators will study the psychological consequences among emergency department (ED) / SAMU (Service d'Aide Médicale Urgente) professionals exposed during the COVID-19 pandemic to high psychological stress due to work overload, changes in practices and fears of contamination.They will evaluate at 9 and 12 months after the end of the second lockdown (July December 2020), post-traumatic stress disorder (PTSD), personal and professional stress, anxiety and depression, burn-out and consumption of anxiolytic products. This is a multi-center study and includes doctors, DE interns and nurses, other paramedics and medical regulatory assistants working in one of the ED or SAMU working during phase 3 of the COVID-19 pandemic. It should make it possible to know the psychological load of the months following the epidemic among health professionals who worked in emergencies during this period and to understand their risk of occurrence of PTSD. These elements are also essential to improve the management of health crises and to put in place preventive measures for health professionals, in particular in anticipation of recurrences, second wave or future new episode.
The Covid-19 pandemic is having a great impact on the long-term mental health and well-being. Reports on the levels of psychological distress are concerning. This can be due to the pandemic, as well as social distancing, employment and economic consequences. Healthcare workers, the elderly, youths, and persons experiencing socio-economic adversity are at risk of developing psychological distress. In this context, healthcare systems risk being overcharged, facing a growing demand. Cognitive Behaviour Therapies managing psychological distress have been formally recommended. WHO has implemented different escalated psychosocial interventions, such as Problem Management Plus, PM+; Doing What Matters in Times of Stress, DWM; and Psychological First Aid, PFA. Their aim is to help individuals manage their stress in order to decrease the occurrence of psychological problems. They do not replace care for severe mental health disorders, but can prevent the deterioration of individuals' mental health. PM+ has previously been found to be effective in situations of endemic conflict or violence in Pakistan and Kenya. The implementation of this program in Europe is being evaluated in the EU H2020 project STRENGHTS, focused in migrants from Syria. In the present trail, the investigators aim to further test its effectiveness in the context of psychological distress resulting from the COVID-19 pandemic. Prior to the present trial, the investigators conducted a qualitative research study among potential beneficiaries and healthcare workers to evaluate the feasibility of DWM and PM+, which showed interest in stepped-care interventions in mental health, particularly if they are technology-based (mobile phones). Our study is embedded in the larger, EU H2020 CORONAVIRUS-funded RESPOND project (Grant Agreement No 101016127). This project granted funding for a multicentric, single-blinded, randomised, controlled trial to evaluate the effectiveness of the stepped-care DWM and PM+ program vs. Care as Usual (CAU). In France, the investigators will focus on persons experiencing socioeconomic adversity, as defined by unstable housing conditions. A recent study showed that most of them are migrants. All subjects (210) will receive PFA and CAU. In addition to PFA and CAU, the treatment group (105 subjects) will receive the intervention DWM (with or without PM+). The primary outcome will be the decrease in symptoms of anxiety and depression from baseline to two-months follow-up.
This study investigates the immune response in the cancer population in Belgium being vaccinated with an approved vaccine types being authorized for use in Belgium. This question needs to be answered to make sure that this vulnerable population is properly protected against possible SARS-CoV-2 infection and that vaccine administration is safe.
