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.

Effect of T cell reactivity in COVID-19 infection and vaccination

Researchers recently developed an immunodiagnostic T cell assay to classify T cell immune responses of the subjects based on their coronavirus disease 2019 infection and vaccination history.

Do reactive oxygen species play a role in fighting COVID-19?

Serum-free thiols are known to reflect the activity of reactive oxygen species in the body, and researchers have been examining the difference in these thiols in COVID-19 patients.

Identifying a recurring pattern in broadly neutralizing antibodies that can target an epitope on SARS-CoV-2

Interesting research decrypts a recurring sequence in antibodies against severe acute respiratory syndrome 2 (SARS-CoV-2) and identifies it to be a board neutralizing antibody that targets a conserved epitope on the SARS-CoV-2 receptor-binding domain (RBD) of the spike protein.
