Immunity following COVID-19 vaccination and natural infection in India

The researchers evaluated immune response markers in a cross-section of people from the Indian state of West Bengal, including those vaccinated with either Covishield or Covaxin, the unvaccinated cohort, and the naturally infected.

Phage-like particle system provides a platform for quick and easy vaccine generation

In this study, researchers report on the development of a monovalent lambda PLP-based vaccine against SARS-CoV-2 or MERS-Cov through decoration with the spike RBD proteins from either virus.

REGEN-COV shown to rapidly reduce SARS-CoV-2 viral load in hospitalized COVID-19 patients

Studies have shown that mortality rates in hospitalized patients with COVID-19 are high, ranging between 10% and 30%. REGEN-COV®, a combination of monoclonal antibodies casirivimab and imdevimab, is approved in the United States and other regions for emergency treatment of COVID-19 outpatients with mild to moderate SARS-CoV-2 infection and post-exposure prophylaxis.

New discovery could lead to the creation of a pan-coronaviruses vaccine

Next generation vaccines for Covid-19 should aim to induce an immune response against 'replication proteins', essential for the very earliest stages of the viral cycle, concludes new research carried out by UCL scientists.

Emergence of SARS-CoV-2 immune escape variants in an immunocompromised patient

A German case study recently published in the journal Nature Communications has characterized a long-term severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection dynamics in an immunosuppressed kidney transplant recipient and provided evidence for the evolution of SARS-CoV-2 into potentially harmful immune escape mutants during persistent infections.

Elusive white blood cells play a role in impaired T cell functions and counts in people with HIV

In a groundbreaking study of people living with HIV, University of Alberta researchers found that elusive white blood cells called neutrophils play a role in impaired T cell functions and counts, as well as the associated chronic inflammation that is common with the virus.

Pfizer-BioNTech COVID-19 vaccine is associated with lower viral load in breakthrough infections

Several vaccines have been rapidly developed to help control the COVID-19 pandemic, including the BNT162b2 vaccine (Pfizer/BioNTech). This severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccine has been shown in both clinical trials and in the real world to be highly efficacious in preventing infection, symptoms, hospitalizations, severe disease, and death related to coronavirus disease (COVID-19).

Drinking alcohol and not exercising are modifiable risk factors for SARS-CoV-2

New research from the United Kingdom suggests several factors that increased the risk of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection involved higher alcohol use, Asian/Asian British ethnicity, and obesity. In addition, moderate but not vigorous exercise of more than 10 hours a week was associated with lower susceptibility to infection.

Increase in SARS-CoV-2 seroprevalence in Irish HCWs during third wave of pandemic

Healthcare workers and people they live with are at an increased risk of contracting severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Hospital healthcare workers (HCWs) worldwide have been found to have a higher number of SARS-CoV-2 infections and higher antibody seroprevalence compared to the general population.
