The new vaccine has been approved today after meeting the required safety, quality and effectiveness standards. The COVID-19 vaccine developed by Oxford University/AstraZeneca has today been given regulatory approval by the Medicines and Healthcare products Regulatory Agency (MHRA) after meeting required safety, quality and effectiveness standards. Following a rigorous, detailed scientific review by the MHRA’s
Severe coronavirus disease 2019 (COVID-19) is characterized by the intense formation of neutrophil extracellular traps (NETs), leading to the occlusion of microvessels, as shown in pulmonary samples. The occurrence of ST-elevated myocardial infarction (STEMI) is a serious cardiac manifestation of COVID-19; the intrinsic mechanism of coronary thrombosis appears to still be unknown. Objective of the
An observational study has launched to evaluate the short- and long-term health outcomes of SARS-CoV-2 infection in children, including multisystem inflammatory syndrome in children (MIS-C), and to characterize the immunologic pathways associated with different disease presentations and outcomes. SARS-CoV-2 is the virus that causes COVID-19. The study, called the Pediatric Research Immune Network on SARS-CoV-2
Children get sick less often than adults due to Covid-19, but children are at risk. This is the key insight from a paper in the Journal of American Medical Association (JAMA), a peer-reviewed medical journal, as the year draws to an end. The paper summarizes the current understanding of how children are affected by Covid-19. So far
Vaccines typically require years of research and testing before reaching the clinic, but in 2020, scientists embarked on a race to produce safe and effective coronavirus vaccines in record time. Researchers are currently testing 64 vaccines in clinical trials on humans, and 19 have reached the final stages of testing. At least 85 preclinical vaccines are under active
he game-changing Oxford vaccination could get the go-ahead “just after Christmas”, a leading expert has said . John Bell, Regius Professor of Medicine at Oxford University, stressed the data behind the jab is looking “better than ever”. The Medicines and Healthcare products Regulatory Agency is examining the vaccine developed by Oxford University and pharmaceutical giant AstraZeneca. With an announcement from the MHRA eagerly anticipated, Prof Bell told
The SARS-CoV-2 spike (S) protein is the target of vaccine design efforts to end the COVID-19 pandemic. Despite a low mutation rate, isolates with the D614G substitution in the S protein appeared early during the pandemic, and are now the dominant form worldwide. In this paper are explored spike conformational changes and the effects of
The SARS-CoV-2 pandemic poses an unprecedented public health crisis. Evidence suggests that SARS-CoV-2 infection causes dysregulation of the immune system. However, the unique signature of early immune responses remains elusive. In this paper the transcriptome of rhesus macaques and mice infected with SARS-CoV-2 was characterized. Alarmin S100A8 was robustly induced in SARS-CoV-2 infected animal models
Recently a distinct phylogenetic cluster (named lineage B.1.1.7) was detected within the COG-UK surveillance dataset. This cluster has been growing rapidly over the past 4 weeks and since been observed in other UK locations, indicating further spread. Several aspects of this cluster are noteworthy for epidemiological and biological reasons and we report preliminary findings below.
There’s a growing variety and availability of tests related to SARS-CoV-2. All types of tests can help healthcare providers make more accurate diagnosis, support better management of individual patients and provide better guidance to manage population risk. Active infection is detected with RT-PCR tests detect the presence of SARS-CoV-2 based on its genetic make up (RNA). These tests
