Viruses often mutate or hide themselves within cells. But by mimicking the way the immune system naturally deals with invaders, researchers reporting in ACS Infectious Diseases have developed a “peptoid” antiviral therapy that effectively inactivates three viruses in lab tests.
Which types of personalities were more hesitant about COVID-19 vaccination during the pandemic’s peak? Extroverts — according to a new study on more than 40,000 Canadians.
Even vulnerable people, who are at risk of severe Covid-19, achieved good antibody levels after three doses of mRNA vaccine.
The availability, speed and effectiveness of genomic sequencing increased dramatically during the pandemic, as scientists worldwide rushed to find ways to track and predict the virus’s movement and evolution. It also was critical in the development of effective vaccines. In an essay published today, two NAU biologists argue that building on this momentum is critical in society’s response to future pandemics, but it requires significant collaboration and investment now, before the next pathogen is threatening society.
The coronavirus pandemic is no longer a national emergency, but the virus that causes COVID-19 isn’t gone—and neither is the risk of getting the disease. For parents, navigating when to get their child vaccinated and knowing how to best protect their child from COVID-19 can be complicated. We spoke to Michael Smit, MD, MSPH, Hospital Epidemiologist and Medical Director of Infection Prevention and Control at Children’s Hospital Los Angeles, to get an update on the latest COVID-19 vaccine information and precautions.
Two clinical trials that will evaluate drugs, biologics, medical devices, and other therapies for long COVID that are sponsored by the National Institutes of Health (NIH) will launch at UTHealth Houston.
Today, the National Institutes of Health launched and is opening enrollment for phase 2 clinical trials that will evaluate at least four potential treatments for long COVID, with additional clinical trials to test at least seven more treatments expected in the coming months. Treatments will include drugs, biologics, medical devices and other therapies.
A mammalian protein previously shown by UT Southwestern microbiologists to inhibit the virus that causes COVID-19 in cell culture also protected live mouse models, significantly limiting infection in the lung cells and diminishing the symptoms. The findings, published in Nature Microbiology, could lead to new strategies to treat COVID-19, which still infects thousands and kills hundreds in the U.S. every week.
Scientists at St. Jude Children’s Research Hospital showed that fixed mutations within a viral population most likely stem from how easy it is to acquire that mutation (i.e., mutation accessibility) rather than just its benefit.
A metabolic by-product that is more prevalent during fasting may supercharge immune cells as they fight infection and disease, reports an early stage study by Van Andel Institute scientists and collaborators.
UC San Diego scientists debut Greengenes2, a massive reference database that could be used to reconcile years of microbiome studies.
Support for early career researchers is about to get a major boost, thanks to a new fellowship fund established by leaders at La Jolla Institute for Immunology (LJI) and Japan-based global pharmaceutical corporation, Kyowa Kirin, Inc.
The global outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and its new variants has created a need for effective disinfection technologies to protect against harmful pathogens. While vaccines offer some protection, their effectiveness against future variants is uncertain. Therefore, additional strategies are important during the pre-vaccine stage.
Programmed cell death, a fundamental biological process that facilitates the elimination of old, damaged, infected, and non-functional cells, plays a crucial role in maintaining the balance between health and disease in the human body.
In a new study, scientists at La Jolla Institute for Immunology (LJI) compared the immune response of individuals who received older versus newer versions of the whooping cough vaccine. The unexpected findings may help explain the recent rise in whooping cough cases and point to potential targets for the next generation of vaccines.
Researchers have found that dozens of viruses respond to quorum sensing or other chemical signals from bacteria.

While the incidence of influenza-associated neuropsychiatric events in children in the United States is unknown, the controversy over the use of a common antiviral medication typically administered to treat flu in children has sparked concern among parents and medical professionals alike. The dilemma about whether the treatment causes neuropsychiatric events or if the infection itself is the culprit, led a group of pediatric researchers at Monroe Carell Jr.
When people who publicly reject COVID-19 vaccines later die from the disease, observers have complex reactions to their fates, a new study suggests. While very few rejoice in the deaths of anti-vaxxers, some people believe those who are dogmatic against vaccines are deserving of worse outcomes – and that reaction is related to the political party affiliation and vaccination status of the person evaluating the anti-vaxxer.
