An antibody is a blood protein that is produced in response to and counteracts an antigen. Antibodies are produced in response to disease and help the body fight against the particular disease. In this way, antibodies help the body develop an immunity to disease.

Long-term effectiveness of Pfizer/BioNTech two-dose regimen mRNA vaccine

A group of scientists from Israel sought to evaluate the long-term effectiveness of the BioNTech/Pfizer mRNA BNT162b2 vaccine.

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.

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.

First detection of SARS-CoV-2 remdesivir resistance in an immunocompromised patient

A research group from the US (led by experts from Yale University School of Medicine) recently presented a case of an immunocompromised female patient with acquired deficiency of B lymphocytes who subsequently developed a protracted course of the infection with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Newly discovered RNA molecule protects mice from emerging SARS-CoV-2 variants

Researchers at Yale School of Medicine have discovered that an RNA molecule that stimulates the body's early antiviral defense system can protect mice from a range of emerging SARS-CoV-2 variants.

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.

Finnish study highlights the need for mRNA COVID vaccine booster shots

A register-based cohort study of the effectiveness of COVID-19 vaccines was performed to help decision-making on providing booster doses to social and healthcare workers (HCWs) like nurses, physicians, dentists, and other professionals in Finland. In addition, it estimated the vaccine effectiveness after the second dose. This study is published on the medRxiv* preprint server.
