As millions of eligible people consider getting a booster shot, many are wondering what the data tells us about the effectiveness of the vaccines, and how much their protection might be waning. The good news is that a growing body of research shows that the vaccines authorized remain highly protective against severe disease and hospitalization
Understanding the process could help scientists look out for new, more infectious variants. Sugars found on the surface of human cells influence COVID-19 infection, according to a University of Alberta-led study that is one of the first to observe this relationship and suggests that cells in the brain might be particularly susceptible. “The idea here is that
An international team of researchers has advanced a new therapeutic approach using stem cells to treat COVID-19. Despite many advances in treating the COVID-19 virus there remains no specific cure for patients with infection. This is especially the case with hospitalised patients who end up in the ICU requiring mechanical ventilation support. Key members of
A recent Monash University study has found six months after recovering from COVID-19 critical illness, one in five people had died, and almost 40 per cent of survivors had a new disability. Led by Professor Carol Hodgson, the study looked at COVID-19 critical illness across Australia between March 6 and October 4, 2020, measuring mortality, new
Safe, effective vaccines against coronavirus disease 2019 (Covid-19) are urgently needed in children younger than 12 years of age. A phase 1, dose-finding study and an ongoing phase 2–3 randomized trial are being conducted to investigate the safety, immunogenicity, and efficacy of two doses of the BNT162b2 vaccine administered 21 days apart in children 6
The winter holidays are approaching, and among the many things to be grateful for this year is that nearly 200 million Americans are fully vaccinated for COVID-19. That will make it safer to spend time with friends and family, though everyone should remain vigilant just to be on the safe side. Though relatively uncommon, breakthrough
PAXLOVID™ (PF-07321332; ritonavir) was found to reduce the risk of hospitalization or death by 89% compared to placebo in non-hospitalized high-risk adults with COVID-19 In the overall study population through Day 28, no deaths were reported in patients who received PAXLOVID™ as compared to 10 deaths in patients who received placebo Pfizer plans to submit the data as
Scientists at Oxford University have identified the gene responsible for doubling the risk of respiratory failure from COVID-19. Sixty percent of people with South Asian ancestry carry the high-risk genetic signal, partly explaining the excess deaths seen in some UK communities, and the impact of COVID-19 in the Indian subcontinent. Previous work has already identified
A new study in the leading journal Science reviewed COVID-19 breakthrough infections among 780,225 Veterans, finding that vaccine protection declined from 87.9% to 48.1% during the 2021 Delta surge in the U.S. The researchers from PHI, the Veterans Affairs Medical Center and the University of Texas Health Science Center found a dramatic decline in effectiveness
Nearly two years since becoming a global pandemic that has killed millions of people, the mystery of which proteins in the SARS-CoV-2 virus are responsible for severe vascular damage that could even lead to heart attack or stroke has not yet been solved. Now, for the first time, a team of experts led by Tel
