Immunogenicity and safety of influenza and COVID-19 multicomponent vaccine in adults age 50 and older

JAMA Network
Peer-Reviewed Publication

About The Study: In this phase 3 study, mRNA-1083, an investigational, multicomponent vaccine against seasonal influenza and SARS-CoV-2, met noninferiority criteria and induced higher immune responses than recommended standard care influenza (standard and high dose) and COVID-19 vaccines against all 4 influenza strains (among those ages 50-64), the 3 clinically relevant influenza strains (among those age 65 and older), and SARS-CoV-2 (all ages), with an acceptable tolerability and safety profile.

Specialized face mask can detect kidney disease with just your breath

American Chemical Society
Peer-Reviewed Publication

Surgical face masks help prevent the spread of airborne pathogens and therefore were ubiquitous during the COVID-19 pandemic. Now, a modified mask could also protect a wearer by detecting health conditions, including chronic kidney disease. Researchers reporting in ACS Sensors incorporated a specialized breath sensor within the fabric of a face mask to detect metabolites associated with the disease. In initial tests, the sensor correctly identified people with the condition most of the time.

A new study published in the Journal of Affective Disorders surveyed 21,000 children in China and found that the association between parental bereavement and school bullying varied by sex of the child and deceased parent, age when the death occurred, and geographical area. Adolescents in rural areas, girls, and older youth (ages 13-17) were at higher risk of bullying after either parent died.

Border closures during COVID briefly reduced support for immigrants and the EU

Universiteit van Amsterdam
Peer-Reviewed Publication

The sudden closure of internal European borders during the COVID-19 crisis had not only practical consequences, but also changed how people thought about immigration and Europe. Recent research from the University of Amsterdam and international partners shows that these measures temporarily undermined trust in the EU and increased hostility toward immigrants—especially among people living near the borders.

BNT162b2 vaccine not only targets COVID-19 virus, but may also help reduce and control innate inflammation

Trinity College Dublin
Peer-Reviewed Publication

Trinity researchers have found that the BNT162b2 COVID-19 vaccine may offer protection beyond its intended, primary target. In a study, recently published in the Clinical Immunology journal, researchers found that the vaccine not only targeted the COVID-19 virus, it also unexpectedly helped to reduce and control innate inflammation to other bacterial and fungal pathogens not related to the vaccine target.

Data collection changes key to understanding maternal mortality trends in the US, new study shows

University of Oxford
Peer-Reviewed Publication

A new study led by researchers at the University of Oxford, published today (28 April) in JAMA Pediatrics, offers fresh insight into trends in maternal mortality in the United States. For the first time, the study disentangles genuine changes in health outcomes from shifts caused by how deaths are recorded. Nevertheless, the study confirms the devastating impact of the COVID-19 pandemic on maternal death rates for women of all racial and ethnic groups.
