Teachers may play a bigger role in COVID-19 transmission in schools than young students do, a small new study from the Centers for Disease Control and Prevention (CDC) suggests. In the study, the researchers investigated COVID-19 transmission in eight public elementary schools in Marietta, Georgia, a suburb of Atlanta, between Dec. 1, 2020, and Jan.
Children are protected from severe COVID-19 because their innate immune system is quick to attack the virus, a new study has found. The research led by the Murdoch Children’s Research Institute (MCRI) and published in Nature Communications, found that specialised cells in a child’s immune system rapidly target the new coronavirus (SARS-CoV-2). MCRI’s Dr Melanie Neeland said the
The cases of rash on mRNA vaccines are almost non-existent and no deaths have occurred. A research published in the medical journal JAMA, points out that the probability of developing anaphylaxis is only 0.000377%, as out of the approximately 17.5 million vaccinations, no deaths occurred, while only 66 people developed anaphylaxis to mRNA vaccines. A
Enrollment has begun to test additional investigational drugs in the Accelerating COVID-19 Therapeutic Interventions and Vaccines (ACTIV) program. ACTIV is a public-private partnership program to create a coordinated research strategy that prioritizes and speeds development of promising COVID-19 treatments and vaccines. The new agents entering the randomized, placebo-controlled study are part of ACTIV-2, an adaptive trial designed to
CAL.20C Variant, Now Found in Nearly Half of Southern California Cases, Is Detected in 19 US States, Washington, D.C., and Six Foreign Countries, Cedars-Sinai Reports A new strain of the coronavirus in Southern California, first reported last month by Cedars-Sinai, is rapidly spreading across the country and around the world as travelers apparently carry the
Editorial emphasizes need for global response. The rise of several significant variants of SARS-CoV-2, the virus that causes COVID-19, has attracted the attention of health and science experts worldwide. In an editorial published today in JAMA: The Journal of the American Medical Association, experts from the National Institute of Allergy and Infectious Diseases (NIAID), part of the
Characterization of the humoral response to SARS-CoV-2, the etiological agent of COVID-19, is essential to help control the infection. The neutralization activity of plasma from COVID-19 patients decreases rapidly during the first weeks after recovery. However, the specific role of each immunoglobulin isotype in the overall neutralizing capacity is still not well understood. In this
Countering COVID-19 mutations and designing updated vaccines could occur at lightning speeds thanks to a new, USC-developed AI framework. USC researchers have developed a new method to counter emergent mutations of the coronavirus and hasten vaccine development to stop the pathogen responsible for killing thousands of people and ruining the economy. Using artificial intelligence (AI),
The Pfizer / BioNTech vaccine is effective against covid-19 variants originating in the UK and South Africa. This is the result of a study published this Monday in Nature Medicine , which showed better results in the first case, the British variant (called B.1.1.7), than in the second, the South African, or B.1.351. The differences, however, are small.
A clinical study led by Dr. Jordan Feld, a liver specialist at UHN’s Toronto Centre for Liver Disease, showed an experimental antiviral drug can significantly speed up recovery for COVID-19 outpatients – patients who do not need to be hospitalized. This could become an important intervention to treat infected patients and help curb community spread,
