May 27th, 2020 - Recent reports have shown a strong association between obesity and the severity of COVID-19 infection, even in the absence of other co-morbidities. After infecting the host cells, SARS-CoV-2 may cause a hyper-inflammatory reaction through the excessive release of cytokines, a condition known as "cytokine storm", while inducing lymphopenia and a disrupted immune response. Obesity is associated w...

May 26th, 2020 - The coronavirus disease 2019 (COVID-19) pandemic caused by SARS-CoV-2 infections has led to substantial unmet need for treatments, many of which will require testing in appropriate animal models of this disease. Vaccine trials are already underway, but there remains an urgent need to find other therapeutic approaches to either target SARS-CoV-2 or the complications arising from viral infection,...

May 26th, 2020 - (Reuters) - U.S. biotech company Novavax Inc has joined the race to test coronavirus vaccine candidates on humans and said it was targeting production of over a billion doses of its vaccine candidate next year. The company, which enrolled its first participants on Monday, said it expected preliminary data on safety and indicators of an immune response from the trial in July. The announcement of...

May 26th, 2020 - The emergence and rapid expansion of the coronavirus disease (COVID-19) require the development of effective countermeasures especially a vaccine to provide active acquired immunity against the virus. This study presented a comprehensive vaccinomics approach applied to the complete protein data published so far in the National Center for Biotechnological Information (NCBI) coronavirus data hub....

May 25th, 2020 - NEW YORK (Reuters Health) - In early April, far more individuals in Los Angeles (LA) County had SARS-CoV-2 antibodies than previously thought, suggesting that confirmed cases don't reveal the true extent of infection in a given community, researchers say. "The findings also suggest that we are far away from herd immunity, and thus we should have a long-term planning horizon in evaluating polici...

May 25th, 2020 - CASCAIS, Portugal (Reuters) - A popular beach town near Lisbon plans to be the first in Portugal to test all of its 200,000 residents for coronavirus antibodies to try and help them enjoy as normal a summer season as possible despite the crisis. Born and bred in Cascais, loved for its beaches and golf courses, 57-year-old Marina Lima was one of the first to enter the tiny testing room when the ...

May 25th, 2020 - The coronavirus disease 2019 (COVID-19) pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has resulted in the death of more than 328,000 persons worldwide in the first 5 months of 2020. Herculean efforts to rapidly design and produce vaccines and other antiviral interventions are ongoing. However, newly evolving viral mutations, the prospect of only temporary immun...

May 23rd, 2020 - The coronavirus disease 2019 (COVID-19) pandemic has created major challenges for all countries around the globe. Retrospective studies have identified hypertension, cardiovascular disease, diabetes and older age as risk factors for high morbidity and mortality from COVID-19. There is a general concern that patients with immune-mediated kidney diseases, namely those on immunosuppressive therapi...

May 22nd, 2020 - Two new studies found that patients with COVID-19, as well as some people who have not been infected with SARS-CoV-2, possess T-cells that target the virus. In the case of those who haven’t had COVID-19, this is likely because they were previously infected with other coronaviruses, such as the common cold. Both studies were able to identify strong T-cell responses to the virus, although they di...

May 21st, 2020 - The recent outbreak of coronavirus disease 2019 (COVID-19), triggered by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) poses an enormous threat to global public health and economies. Human coronaviruses normally cause no or mild respiratory disease but in the past two decades, potentially fatal coronavirus infections have emerged, causing respiratory tract illnesses such as p...

May 21st, 2020 - Pregnant women have a disproportionately high risk of complications from other types of viral pneumonia; however, little is known about the full impact of coronavirus disease 2019 (COVID-19) in pregnancy. Pregnant women are uniquely susceptible to severe illnesses caused by viral infection, possibly due to the shift from cellular to humoral immunity during pregnancy and the puerperium [1].

May 21st, 2020 - Editor's note: Find the latest COVID-19 news and guidance in Medscape's Coronavirus Resource Center. A successful vaccine for prevention of SARS-CoV-2 infection will probably need to incorporate T-cell epitopes to induce a long-term memory T-cell immune response to the virus, Mehrdad Matloubian, MD, PhD, predicted at the virtual edition of the American College of Rheumatology's 2020 State-of-th...

To analyze the immune status of newborns from mothers with COVID-19 in the third trimester. Along with collecting the clinical data from 51 newborns and their respective mothers, we also r...

May 21st, 2020 - (Reuters) - A quarter of Americans have little or no interest in taking a coronavirus vaccine, a Reuters/Ipsos poll published on Thursday found, with some voicing concern that the record pace at which vaccine candidates are being developed could compromise safety. While health experts say a vaccine to prevent infection is needed to return life to normal, the survey points to a potential trust i...

May 21st, 2020 - (Reuters) - The U.S. Food and Drug Administration on Thursday identified 27 coronavirus antibody tests that should no longer be sold in the United States, following up on new regulations meant to weed out dubious tests and players that had entered the country under loose rules set in March.
