Filter by:The current study primarily aims to determine the status of vaccination in enrolled cancer patients and identify barriers to coronavirus disease 2019 (COVID-19) vaccination in cancer patients who have not been vaccinated. Secondary objectives include determining the rate of vaccination in those who have ever been COVID-19 positive and those who have never been COVID-19 positive. The study team also seeks to determine factors associated with vaccine-acceptance and vaccine-hesitancy in the adult cancer population, identify side effects of COVID-19 vaccines in vaccinated cancer patients and to examine the effect of COVID-19 vaccination on overall clinical outcome in cancer patients. The study team will be conducting telephone interviews/surveys with up to130 adult cancer patients for data collection.
Aim of the study is to evaluate the presence of SARS-CoV2 RNA in the saliva of patients with suspected or confirmed COVID-19 in order to validate the analysis of this type of sample for the diagnosis of SARS-CoV2 infections.
COVID-19 caused by SARS-CoV-2 virus has affected the lives of millions of individuals globally and also severely strained the medical community. Pre-symptomatic and asymptomatic SARS-CoV-2 positive individuals far outnumber the symptomatic ones or those with severe disease. The transmission potential of SARS CoV-2 is potentially greater than earlier viral outbreaks of SARS-CoV and MERS-CoV.Routine measures of social distancing, personal hand hygiene and limited outdoor contact activities have shown benefits to limit corona virus infection. However, the role of vitamin D in SARS-CoV-2 infection is sparingly explored despite the knowledge of an immunomodulatory role and protective effect of vitamin D against viral infections. Meta-analysis of five clinical trials of vitamin D supplementation found that those receiving vitamin D supplementation had fewer respiratory tract infections (odds ratio = 0.58 (95%CI, 0.42 - 0.81).Any immune-modulatory effect of vitamin D is likely to be observed at levels which are considered higher than that required for normal bone metabolism.
This is a randomized, observer-blind, parallel-controlled study, for evaluation of safety and immunogenicity of sequential immunization of a recombinant COVID-19 vaccine (adenovirus type 5 vector) in Chinese healthy adults aged 60 and above after the priming vaccination of inactivated vaccine. 300 healthy subjects aged 60 and above will be recruited in this study. Of them, 200 subjects who have been vaccinated with two dose of inactive SARS-CoV-2 vaccine will be recruited and randomized at a 1:1 ratio to receive a booster dose of inactivated SARS-CoV-2 vaccine or recombinant SARS-CoV-2 Ad5 vectored vaccine at 3~6 months later. Other 100 subjects who have been vaccinated with one dose of inactivated SARS-CoV-2 vaccine will be recruited and randomized at a 1:1 ratio to receive a booster dose of inactivated SARS-CoV-2 vaccine or recombinant SARS-CoV-2 Ad5 vectored vaccine at 1~3 months later. The occurrence of adverse events within 28 days and serious adverse events within 6 months after vaccination will be observed. In addition, blood samples will be collected on day 0 before the boosting with ad5 vectored vaccine and on day 14, 28 and month 6 after the boosting. Serum antibody levels, cellular immune responses and the subgroups or germlines of the specific B cells will be analyzed. Each subject will remain in this study for approximately 6 months.
The purpose of this study is to evaluate the safety and efficacy of mRNA COVID-19 vaccines in: • People with prior COVID-19 (SARS-CoV-2 infection) who were in the ACTIV-2/A5401 study. And • People who have never had COVID-19 (SARS-CoV-2 infection).
This study is looking at the role of acupuncture as a treatment for olfactory dysfunction in patients who tested positive for COVID-19.
This study will deploy a multimodal pragmatic intervention to improve vaccine uptake in priority populations and address vaccine hesitancy to improve access by using a proactive organized population-based outreach leveraging health information technology with tailored navigation support to address mistrust and social barriers.
The purpose of this study is to assess the safety and immunogenicity of MVC-COV1901 vaccine compared to placebo in participants aged ≥ 12 to < 18 years.
Phase 2b clinical trial to evaluate the safety and efficacy of intranasal application of GX-03 as a treatment and prevention for COVID-19.
To reach herd immunity for COVID-19, experts estimate that 70% of the population will need to be vaccinated. However, vaccination rates have begun to slow down in the United States. The investigators will partner with Philadelphia to launch a COVID-19 vaccination sweepstakes, in which residents will be eligible to win if they have received at least one dose of the COVID-19 vaccine prior to a given drawing. Drawings will be held every two weeks; multiple prizes of various sizes will be awarded in each drawing. Half of the prizes in each size category in each drawing will be awarded to residents of a zip code that is randomly selected from a pre-defined list of under-vaccinated zip codes (this zip code will be announced at the start of each 2-week drawing period), the other half will be awarded to residents outside of that selected zip code. The investigators will analyze vaccination rates in Philadelphia as compared with neighboring regions before, during, and after the specified time period, as well as analyze vaccination rates in the three selected zip codes compared to the other zip codes that could have been targeted (the residual set of under-vaccinated zip codes) to determine the effectiveness of the sweepstakes at encouraging vaccinations.
