U.S. schools operating in-person have experienced low transmission of the Chinese coronavirus, particularly when mitigation strategies such as masking and social distancing are in place, U.S. Centers for Disease Control and Prevention (CDC) Director Rochelle Walensky stressed on Friday, citing new findings by the health agency. Under President Joe Biden, the CDC has expressed support
The key question in 2021 is whether the new strains of coronavirus will be able to eradicate the vaccine-induced immunity. This paper on JAMA by John P Moore and Paul A Offit of Cornell and Pennsylvania Universities has been recently published on JAMA. The protection that vaccines provide against COVID-19 infection is mediated primarily by
Efficacy and safety of corticosteroids in patients with SARS-CoV-2 infection still are debated. Because large randomized clinical trials (RCTs) and a well-conducted meta-analysis on the use of corticosteroids, focused on patients with coronavirus disease (COVID-19) in intensive care units, recently were published, a meta-analysis of RCTs on corticosteroids therapy in patients with different disease severity
An international team of researchers has characterized the effect and molecular mechanisms of an amino acid change in the SARS-CoV-2 Spike protein N439K. Viruses with this mutation are both common and rapidly spreading around the globe. The peer reviewed version of the study appears January 25 in the journal Cell. Investigators found that viruses carrying this
In the United States alone, over 100,000 people are on the organ transplant list. Around 17 of these people will die per day without having received the transplant. It’s clear that organs from human donors will never be adequate for everyone looking for a transplant. Thus, scientists have been researching alternatives, such as using organs made from repurposed stem
Women and children bear substantial morbidity and mortality as a result of armed conflicts. This paper published in The Lancet focuses on the direct (due to violence) and indirect health effects of armed conflict on women and children (including adolescents) worldwide. It was estimate that nearly 36 million children and 16 million women were displaced
The Clalit Research Institute is currently examining the effect of the vaccine against the coronavirus developed by Pfizer. Preliminary data show that 14 days after the injection of the first vaccine, there is a real decrease in the rate of infection in the corona . The study compared the infection data of about 200,000 people aged 60 and over who
As of January 20, 2021, a total of 24,135,690 cases of coronavirus disease 2019 (COVID-19) and 400,306 associated deaths had been reported in the United States (https://covid.cdc.gov/covid-data-tracker/#cases_casesper100klast7days). On December 18, 2020, the Food and Drug Administration (FDA) issued an Emergency Use Authorization (EUA) for Moderna COVID-19 vaccine administered as 2 doses, 1 month apart to
Scientists at Children’s Hospital Los Angeles develop newer CAR T therapy that promises to be more effective and less toxic for children with neuroblastoma. Chimeric Antigen Receptor T-cell therapy—CAR T—has revolutionized leukemia treatment. Unfortunately, the therapy has not been effective for treating solid tumors including childhood cancers such as neuroblastoma. Preclinical studies using certain CAR
Following implementation of vaccination, reports of anaphylaxis after the first dose of the Pfizer-BioNTech COVID-19 vaccine emerged.Anaphylaxis is a life-threatening allergic reaction that occurs rarelyafter vaccination, with onset typically within minutes to hours.Notifications and reports of suspected severe allergic reactions and anaphylaxis following vaccination were captured in the Vaccine Adverse Event Reporting System (VAERS), the
