Study provides evidence for spike protein-independent attenuation of SARS-CoV-2 Omicron variant

A new study provided the structural basis for a robust interaction between the receptor-binding domain of the SARS-CoV-2 Omicron spike protein and mouse ACE2.

Study points to vagus nerve dysfunction as a central pathophysiological feature of long COVID

New research to be presented at this year's European Congress of Clinical Microbiology and Infectious Diseases (ECCMID 2022, Lisbon, 23-26 April) suggests that many of the symptoms connected to post-COVID syndrome (PCC, also known as long COVID) could be linked to the effect of the virus on the vagus nerve – one of the most important multi-functional nerves in the body.

Identifying and targeting ‘fence-sitters’ early in pandemic could help reduce vaccine hesitancy

Identifying adults who are ambivalent about vaccines early in a pandemic and finding community leaders who can help spread reliable information within their communities could help reduce vaccine hesitancy, according to a new University of Michigan study.

Performance of SARS-CoV-2 antibodies improves only after previous infection, not vaccination

New research to be presented at this year's European Congress of Clinical Microbiology & Infectious Diseases (ECCMID 2022, Lisbon, 23-26 April) shows that, although over time the number of SARS-CoV-2 antibodies falls in both previously infected and vaccinated patients, the performance of antibodies improves only after previous infection (and not vaccination).

New insights into the effects of COVID-19 vaccination on dialysis patients

Two studies in CJASN offer a better understanding of the effects of COVID-19 vaccination on individuals with kidney failure who are undergoing long-term dialysis.

Hazards of persistent and new clinical sequelae caused by SARS-CoV-2 infection among elderly patients

A new study estimated the risk and hazards of persistent and new clinical sequelae of the SARS-CoV-2 infection among elderly patients (above 65 years or older) during the post-acute phase of the infection.

COPD patients more compliant with COVID-19 restrictions in the UK

A new study reports on the tendency among COPD patients in the UK to practice social distancing, compared to the public at large, during the COVID-19 pandemic.

The impact of COVID-19 on people with systemic autoimmune rheumatic diseases

A survey demonstrated that patients with systemic autoimmune rheumatic diseases commonly experience augmented disease severity and disrupted treatment regimens of disease-modifying antirheumatic drugs after acute COVID-19 course.

11 Feb 2022

Model shows booster doses and antiviral pills may enable relaxation of SARS-CoV-2 social distancing

Researchers suggest that social distancing could be relaxed in order to reduce the number of severe cases of COVID-19, rather than stop the transmission of the SARS-CoV-2.

11 Feb 2022

SARS-CoV-2 nucleocapsid G215C variation may explain Delta severity

A new study shows that the SARS-CoV-2 nucleocapsid protein has unique properties that allow the virus to become more infective in the presence of certain mutations.

11 Feb 2022

Study investigates population immunity to SARS-CoV-2 through heterogenous pathways

A new study demonstrates COVID-19 vaccine-specific differences in the antibody responses and memory B-cell immunity in a sample population comprising of 197 vaccinated individuals in Mexico.

11 Feb 2022

New COVID-19 test can determine if individuals have been vaccinated, infected, both, or neither

Researchers have created a new T cell assay that allows discrimination of COVID-19 infection and vaccination, as well as the order in which these occurred.

Novel molecule shows ability to inhibit the replication of all coronaviruses

Uppsala researchers have succeeded in designing a molecule that inhibits the replication of coronaviruses and that has great potential for development into a drug suitable for treating COVID-19.

10 Feb 2022

Study identifies SARS-CoV-2 variants with potential to escape the immune system's T cell response

A number of existing strains of SARS-CoV-2, as well as other future variants that could arise, have the potential to escape the immune system's cytotoxic T cell response in some portion of the population.

Study suggests SARS-CoV-2 Omicron showed increased household transmission and immune evasion in Norway

Researchers from Norway used contact tracing data to measure and compare the household secondary attack rate of the SARS-CoV-2 Omicron and Delta variants at a time of prominence of both variants in the country.

Spillover of SARS-CoV-2 Omicron variant infection in white-tailed deer in New York

Researchers detected evidence for SARS-CoV-2 Omicron variant exposure in the white-tailed deer population inhabiting Staten Island in New York.

Study reports accumulation of SARS-CoV-2 RNA in sewer biofilms

During the COVID-19 pandemic, monitoring the levels of SARS-CoV-2 RNA in wastewater entering treatment plants has been one way that researchers have gauged the disease's spread.

Excess COVID-19 mortality in Eastern Europe linked to lower vaccination rates and weak implementation of regulations

Researchers assessed the association between excess COVID-19 mortalities with vaccination rate, and regulation enforcement, in Eastern European countries that witnessed high COVID-19 mortalities throughout 2021.

Study: Almost a third of older adults infected with covid-19 develop new conditions

Almost a third (32 of every 100) of older adults infected with covid-19 in 2020 developed at least one new condition that required medical attention in the months after initial infection, 11 more than those who did not have covid-19, finds a US study published by The BMJ today.
