The largest trial to date assessing the use of convalescent plasma therapy for COVID-19 has revealed that the treatment is effective in 76% of patients, with no adverse effects. Further research is needed to evaluate how to optimize this therapy.
Data from the Adaptive COVID-19 Treatment Trial (ACTT) has demonstrated that remdesivir treatment reduces recovery time in patients hospitalized with severe SARS-CoV-2 infections, requiring supplemental oxygen therapy. The results support remdesivir as the standard treatment for patients hospitalized with COVID-19.
The first human trial testing a potential COVID-19 vaccine has been successful, with initial results suggesting the vaccine is safe and capable of generating an immune response against SARS-CoV-2 in humans.
Researchers have demonstrated that two COVID-19 vaccine candidates can protect against COVID-19 in primates, with re-exposure triggering an immune response in rhesus macaques.
After analyzing data from SARS survivors, a team of researchers from across the globe has identified an antibody that can inhibit related coronaviruses, including SARS-CoV-2. The antibody, termed S309, is now on an accelerated path towards clinical trials.
Researchers have demonstrated that cigarette smoke causes an increased expression of Angiotensin Converting Enzyme 2 (ACE2), the SARS-CoV-2 receptor, in the lungs. This suggests that individuals who smoke could be more susceptible to severe SARS-CoV-2 infections.
An exploratory study testing interferon α-2b treatment for COVID-19 has demonstrated improved viral clearance in a small cohort of patients. The researchers also observed a reduction in levels of inflammatory proteins in COVID-19 patients after treatment.
Researchers have discovered that numbers of microRNAs responsible for attacking SARS-CoV-2 are reduced in the elderly and those with chronic health conditions, which could explain their vulnerability.
Researchers at the Korea Institute of Science and Technology (KIST) and Catholic University of Korea (CUK) have developed a vaccine platform against MERS coronavirus (MERS-CoV) that could be used to develop a vaccine for COVID-19.
A novel COVID-19 symptom tracker app, which has already had over 3 million users, could help identify geographical hotspots and prevent future COVID-19 outbreaks.
