New report on 1.23 million breakthrough symptomatic SARS-CoV-2 infections by vaccine

A new research letter evaluates whether the estimated vaccine effectiveness changes against infection over time.

Double-dose mRNA COVID vaccines effective among dialysis patients

Researchers assess the impact of lesser initial vaccine response and subsequent waning antibody levels on clinical outcomes among maintenance dialysis.

Study suggests spike mutation makes SARS-CoV-2 Omicron milder

The Omicron spike is relatively poorly cleaved and impaired in mediating cell-cell fusion and syncytia formation, contrary to predictions.

Researchers discover antibodies that neutralize omicron and other SARS-CoV-2 variants

An international team of scientists have identified antibodies that neutralize omicron and other SARS-CoV-2 variants. These antibodies target areas of the virus spike protein that remain essentially unchanged as the viruses mutate.

COVID isolation and quarantine period for general population shortened by CDC

Given what we currently know about COVID-19 and the Omicron variant, CDC is shortening the recommended time for isolation from 10 days for people with COVID-19 to 5 days, if asymptomatic, followed by 5 days of wearing a mask when around others.

SARS-CoV-2-induced kidney damage

Severe acute respiratory syndrome coronavirus 2 (SARS‑CoV‑2) infects the kidneys and contributes to tissue scarring, as shown by researchers from the RWTH Uniklinik Aachen, Germany, and Radboudumc, The Netherlands. The developed scar tissue in the infected kidneys may suggest a possible impact on kidney outcomes in the long term.

APOE4 allele gene linked to increased risk of severe COVID-19

A study conducted at the University of Helsinki and the Helsinki University Hospital suggests that the APOE4 allele may also increase cerebral microhemorrhages related to COVID-19 and associate with mental fatigue related to long COVID.

Uptake of COVID-19 vaccine doses increases before Christmas in England

Thousands more first and second doses were administered last week compared with the week before, as the public are today reminded that the offer of a vaccine is still available and encouraged to come forward to protect themselves against Omicron.

Cancer patients who had breakthrough COVID-19 remain at high risk for hospitalization, death

The first study to evaluate the clinical characteristics and outcomes of fully vaccinated patients with cancer who had breakthrough COVID-19 infections indicates they remained at high risk for hospitalization and death.

SARS-CoV-2 Alpha variant mutated to evade the immune system

The SARS-CoV-2 Alpha (B.1.1.7) variant mutated to evade our 'innate immune system', helping establish it as the world's first 'Variant of Concern', finds a new study led by researchers at UCL and the Quantitative Biosciences Institute, University of California San Francisco.

Study helps explain why mRNA vaccines have been successful at preventing severe COVID-19

Washington University in St. Louis student Julian McCall receives a dose of Pfizer's mRNA-based COVID-19 vaccine.

Omicron variant of SARS-CoV-2 manifests striking antibody evasion

A new study from Columbia researchers, in collaboration with scientists at the University of Hong Kong, adds more evidence that the omicron variant can evade the immune protection conferred by vaccines and natural infection and suggests the need for new vaccines and treatments that anticipate how the virus may soon evolve.

Study hints subtle differences in the quality of immune response based on COVID-19 severity

Infection-fighting B cells retain better memory of the coronavirus spike protein in University Hospital patients who recover from less-severe cases of COVID-19 than in those recovering from severe COVID-19, a new study suggests.

Scientists identify a new Achilles' heel of influenza virus

Scientists at Scripps Research, University of Chicago and Icahn School of Medicine at Mount Sinai have identified a new Achilles' heel of influenza virus, making progress in the quest for a universal flu vaccine.

Pfizer vaccine associated with lower risk of SARS-CoV-2 infection and hospitalization in middle-aged adults

New findings suggest that the Pfizer-BioNTech mRNA COVID-19 vaccines provide extra protection against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) than AstraZeneca.

24 Dec 2021

Pfizer-BioNTech booster shot may offer better immunity than a two-dose regimen

A new study suggests that the immune response against severe acute respiratory syndrome coronavirus 2 is greater with a three-dose regimen than a two-dose regimen.

New study provides a mutational analysis of SARS-CoV-2

A new study investigates mutational waves in structural and non-structural protein evolutions of SARS-CoV-2 to better understand the virus’s evolution and epidemiology.

24 Dec 2021

Children with pre-existing immunity to common cold demonstrate better protection against COVID-19

New data shows that, compared to adults, children infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) preferentially activate pre-existing acquired immunity to prevalent common cold coronaviruses that cross-react with SARS-CoV-2 and protect them from severe disease.

Are our bowel habits written in our DNA?

In this interview, News-Medical talks to Dr. Mauro D’Amato about how there could be clues about the regularity of bowel movements within our genes.

Scientists detect COVID-19 infection in white-tailed deer in 6 Ohio locations

Scientists have detected infection by at least three variants of the virus that causes COVID-19 in free-ranging white-tailed deer in six northeast Ohio locations, the research team has reported.
