NewsSymptoms of long-COVID can last up to two years after infection with COVID-19
According to a study of the COVICAT cohort, almost one in four people infected with SARS-CoV-2 suffered from long-COVID. In more than half of them the symptoms persisted for two years.

NewsCause of post-COVID inflammatory shock in children identified
MIS-C is a serious inflammatory shock that affects children and can occur several weeks after a COVID infection. Researchers have found that reactivation of a pre-existing, dormant infection with the Epstein-Barr virus triggers an excessive inflammatory response.

NewsMulti-dose vaccines administered in the same site boost immune response
New research suggests that receiving multiple doses of a vaccine in the same limb leads to faster antibody development, an important strategy for providing immunity as quickly as possible during a pandemic or disease outbreak.

NewsInhaled COVID vaccine study begins recruitment for phase-2 human trials
Researchers have started a phase-2 clinical trial on a next-generation, inhaled COVID-19 vaccine. Findings from the phase-1 trial indicate that the vaccine is more effective at inducing immune responses than traditional injected vaccines are.

NewsBAADesign enables the immune escaped etesevimab fully-armed against SARS-CoV-2 Omicron subvariants
BAADesign offers a powerful tool for reengineering monoclonal antibodies to combat emerging SARS-CoV-2 variants, providing a scalable solution for future pandemic preparedness, according to a new study.

NewsScientist who deployed glowing stars to detect disease named fellow of the Royal Society of Chemistry
The man who turned the science of glow-in-the-dark stars into ways to detect disease, Professor Richard Willson, has been elected as a fellow of the Royal Society of Chemistry.

NewsNew COVID-flu vaccine platform could provide broad, lasting protection
Researchers have developed a new vaccine platform that could provide more robust, longer-lasting protection from both COVID-19 and influenza, and broader immunity to different flu strains.

NewsLung abnormalities seen in children and teens with long COVID
An advanced type of MRI uncovers significant lung abnormalities in children and adolescents with long COVID, according to a new study. PREFUL MRI doesn’t require the use of radiation or intravenous contrast agents and can be done while the patient breathes freely.

NewsPaxlovid’s impact on hospitalization and death in COVID-vaccinated older adults far weaker than previously thought
A new study overturns the assumption that Paxlovid’s effectiveness in reducing COVID-19 hospitalizations and deaths in unvaccinated adults also applies to vaccinated adults.

NewsMachine learning framework can decipher immune system’s record of past infections
A novel machine learning framework can decipher an individual’s immune system’s record of past infections and diseases, providing a powerful tool with the potential for diagnosing autoimmune disorders, viral infections, and vaccine responses with precision.

NewsNew modeling approach could help design antivirals for shape-shifting viruses
New research utilizes an innovative computational modeling approach to capture the complex and diverse shapes that viral proteins can adopt.
-
NewsBat genome signposts new potential pathway to fight viruses with genomic characterization
A promising discovery has been made from a study that deciphers how bats are more resistant to viral infections than human using genome annotations of transposable elements in bats to pave a way for adapting the bats’ immunity against future viral outbreaks.

NewsNasal COVID-19 vaccine to enter US clinical trials
A nasal vaccine for COVID-19 is poised to enter a phase 1 clinical trial in the U.S. after an investigational new drug application from Ocugen, Inc. was approved by the Food and Drug Administration (FDA).

NewsVirus that causes COVID-19 increases risk of cardiac events
A new study found severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection was associated with the rapid growth of plaque in the coronary arteries and an increased risk of cardiovascular events.
-
NewsNew method offers faster response to new virus variants
Researchers present a promising approach for swift identification of mutations that are crucial for the immune escape that enables the rapid adaptation of vaccines to new virus variants. It is based on a previously established method called mutational scanning.

NewsStudy investigates ozonated water’s effectiveness against SARS-CoV-2 in saliva
A research group examined the human salivary organic components, amylase, mucin, and urea, and ozonated water’s effect on SARS-CoV-2 in the presence of these components.
-
NewsVentilation in hospitals could cause viruses to spread further
Increased use of ventilation and air cleaners, designed to mitigate the spread of viral infections in hospitals, is likely to have unpredictable effects and may cause viral particles to move around more, according to a new study.
-
NewsResearchers in Brazil discover a gene that may afford protection against COVID-19
During the pandemic, health worker Maria Tereza Malheiros Sapienza’s curiosity was aroused by her immunity to SARS-CoV-2, even though her husband was infected twice. A new study reveals that an overexpression of IFIT3 protein was responsible.
-
News New tool can detect fast-spreading SARS-COV-2 variants before they take off
By analysing millions of viral genome sequences from around the world, a team of scientists has uncovered the specific mutations that give SARS-CoV-2 a ‘turbo boost’ in its ability to spread.
