Despite its advantages over other vaccine technologies for Covid-19, adenovirus vector vaccines are likely to be tripped up by pre-existing antibodies to the vectors used and the need for a second injection to boost protection. CanSino Biologics’ Ad5-nCoV and Johnson & Johnson’s AdVac platform-based vaccine use a human adenovirus vector, but a significant chunk of people may [...]
When the first coronavirus cases in Chicago appeared in January, they bore the same genetic signatures as a germ that emerged in China weeks before. But as Egon Ozer, an infectious-disease specialist at the Northwestern University Feinberg School of Medicine, examined the genetic structure of virus samples from local patients, he noticed something different. A change [...]
Park Systems presents “NanoScientific Symposium on Nano Applications for a Changing World” sponsored by Physics World and Nanotechnology World Association. Park Systems launched this online event for researchers and scientists in nanoscience and nanotechnology to share data on how new nano applications under research will lead to discoveries that have a tremendous positive impact [...]
Notwithstanding the wishful thinking of certain irresponsible and incompetent public figures, the only options to control and deal with the spread of the Severe Acute Respiratory Syndrome Virus 2 (SARS-CoV-2) are fast, cheap, reliable, and portable means of diagnosing COVID-19 infection (the name of disease caused by SARS-CoV-2); therapeutics to treat the infected; and [...]
From the Annals of Neurology: In less than 6 months, the severe acute respiratory syndrome‐coronavirus type 2 (SARS‐CoV‐2) has spread worldwide infecting nearly 6 million people and killing over 350,000. Initially thought to be restricted to the respiratory system, we now understand that coronavirus disease 2019 (COVID‐19) also involves multiple other organs including the central [...]
A cheap steroid has become the first life-saving treatment in the Covid-19 pandemic, described by scientists as a major breakthrough and raising hopes for the survival of thousands of the most seriously ill. Dexamethasone is cheap, available from any pharmacy, and easily obtainable anywhere in the world. Investigators said the drug was responsible for [...]
Clinical researchers are this week set to begin human trials of a new coronavirus vaccine developed by researchers at Imperial College London. The study will be the first time the vaccine has been trialled in humans and will test whether it is well-tolerated and produces an effective immune response against COVID-19. In the long-term, a viable [...]
A form of the novel coronavirus which has become the dominant type in much of the world may have done so thanks to a mutation that allows it to better latch onto human hosts’ cells, new research indicates. Lab tests performed by US-based Scripps Research, in a study which has not yet been peer-reviewed, showed that [...]
A widely available and inexpensive drug that is used to ease the symptoms of indigestion may prove a worthy contender for treating COVID-19 infection in those whose disease doesn’t require admission to hospital, suggest the findings of a small case series, published online in the journal Gut. The effects were felt within 24 to 48 [...]
One of the most common COVID-19 tests involves a long swab pressed deep into the nasal cavities – and while the test can be administered quickly, it has been described as unpleasant and uncomfortable. Now researchers at The Ohio State University are working on a testing system that would require a simple exhaled breath. [...]
