A study by researchers at Washington University School of Medicine in St. Louis has found that repeat vaccination with updated versions of the COVID-19 vaccine promotes the development of antibodies that neutralize a wide range of variants of the virus that causes COVID-19, as well as related coronaviruses.
Vaccines remain the gold standard of protection against dangerous pathogens, but take considerable time and vast resources to develop. Rapidly mutating viruses such as SARS-CoV-2 can blunt their effectiveness and even render them obsolete.
Scientists examined cognitive impairment and recovery time in patients following COVID-19 infection.
Rutgers Health researchers found that long COVID is associated with active inflammatory changes in the nervous system, but the condition is distinct from Alzheimer’s disease and other neurodegenerative disorders.
Changing people’s behavior until a vaccine could be developed prevented roughly 800,000 COVID-19 deaths in the U.S., according to new CU Boulder and UCLA research. But the authors stress that interventions like lockdowns and school closures came at great economic and social cost.
Member States of the World Health Organization (WHO) were due to converge on text for a global pandemic agreement during their ninth and final negotiating session in March; however, insufficient progress was made in those two weeks, in terms of finding consensus.
A group of UC San Diego researchers, centered at UC San Diego's Institute for Network Medicine, teamed up with rheumatologists at the University of Leeds in the United Kingdom to solve a medical mystery.
