Omicron evades roughly twice the number of SARS-CoV-2 neutralizing antibodies than Delta

New study results highlight that Omicron has an increased affinity to ACE-2 receptors, therefore, has increased infectivity, viral load, and transmissibility compared to other variants of concern, including the Delta variant.

Extended interval between second and third vaccination beneficial against SARS-CoV-2 Omicron variant

A new study proposes a multi-boost vaccine strategy with a longer duration between the second and third dose, as that would be beneficial in acquiring immunity against severely mutated SARS-CoV-2 variants.

Study suggests nitazoxanide fails to reduce the severity of SARS-CoV-2

A new study shows that the optimization of nitazoxanide formulations may allow the review of the potential use of the drug for the treatment of SARS-CoV-2 infection.

Scientists identify a panel of nanobodies with good neutralizing efficacy against SARS-CoV-2 variants of concern

A team of scientists from Canada has recently characterized a panel of nanobodies against the spike protein of SARS-CoV-2.

Defensosomes can act as decoys to protect against SARS-CoV-2

In a new study, researchers from New York University have been examining the ability of defensosomes to combat SARS-CoV-2 infection.

Furin cleavage site similarities in SARS-CoV-2 and rodent coronavirus indicate common wildlife host

New study findings show that AcCoV-JC34 is the only luchacovirus containing a –RR-R- motif that is identical to the one found in SARS-CoV-2.

Exploring the Mediterranean diet as a potential strategy against SARS-CoV-2

A study found that the Mediterranean diet, when combined with non-smoking and regular physical activity, can lower susceptibility to SARS-CoV-2.

Scientists develop a detailed epidemiological model for the spread of COVID-19 in nursing homes

Researchers from TU Graz and Complexity Science Hub (CSH) Vienna have developed a detailed epidemiological model for the spread of the coronavirus in nursing homes. This enables optimal prevention strategies to be identified, as practical experience in Caritas nursing homes has shown.

Importance of pneumococcal vaccination during the COVID-19 pandemic

A new study discusses the necessity and role of pneumococcal immunization in strengthening the global health system amid the current COVID-19 pandemic.

‘An Arm and a Leg’: The rapid-test edition: Who’s making a buck?

Rapid, at-home covid-19 tests are close to essential if you want to see friends and family this holiday season, and do your best to stay safe.

As pandemic wears down hospital staff, one town offers groceries to say thanks

This mountain community — which comes alive during the winter ski season and annual Sundance Film Festival — is home to the Park City Hospital, which has 460 employees.

Researchers identify new mechanism for DNA invasion of adenoviral COVID-19 vaccines

Adenoviruses have a linchpin protein that stabilizes their DNA until it reaches the infected cell's nucleus. The protein then detaches from the viral genome, and the virus uncoats. Only then are the genes released into the nucleus, which is necessary for the production of new viruses.

Two-dose ChAdOx1 vaccine protection wanes after three months

New research reported in the journal The Lancet examines the temporal association between the two-dose ChAdOx1 nCoV-19 (Oxford-AstraZeneca) vaccination regimen and the risk of severe outcomes from COVID-19 in Scotland vs. Brazil, where the Delta variant of SARS-CoV-2 was dominant and rare, respectively.

Broad neutralization of SARS-CoV-2 spike protein by an unconventional antibody fragment

A new preprint research paper posted to the bioRxiv* server examines the nature and effects of the spike mutations and identifies a vulnerable point that could help develop broad-spectrum protection against circulating variants.

Government to provide additional support for businesses affected by Omicron variant in the UK

Recognizing that the rise of the Omicron variant means some businesses are likely to struggle over the coming weeks, the government is providing one-off grants of up to £6,000 per premises for businesses in the hospitality and leisure sectors in England.

National U.S trial confirms effectiveness of mRNA COVID-19 vaccines

In a recent study, published in the Annals of Internal Medicine, scientists conducted a target trial emulation study and documented that among the elderly in the U.S. (with significant comorbidities), the efficacy of messenger RNA (mRNA) vaccines was much lower in terms of preventing infection, than previously reported. However, the effectiveness against death was found to be high.
