Why do some people develop persistent lung sequelae after severe COVID-19?

Clinical presentation following severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) ranges from mild self-limiting illness to severe respiratory failure. Many studies have analyzed the early acute phases of coronavirus disease 2019(COVID-19), but few focused on the longer-term sequelae following infection.

BA.4/BA.5 mutations reduced responsiveness of epitope-specific T cells with original mRNA vaccine

A new study in the journal Viruses examines the phenomenon of breakthrough infections due to the evasion of T-cell immunity by the Omicron BA.4/BA.5 subvariants, showing this to be due to spike gene mutations.

Study demonstrates the benefits of vaccination and boosting in reducing COVID-19 transmission

Vaccination and boosting, especially when recent, helped to limit the spread of COVID-19 in California prisons during the first Omicron wave, according to an analysis by researchers at UC San Francisco that examined transmission between people living in the same cell.

COVID-19 prevention and control measures associated with decrease in influenza activity

A recent study provides preliminary evidence of the long-term relationship between prevention and control measures and influenza transmission in China during the COVID-19 pandemic, accounting for the impact under various prevention and control levels. This study, the first of its kind, was published in Health Data Science, a Science Partner Journal.

Alveolar macrophages present as antigens to promote virus-specific CD8+ T cell expansion

The human immune system is a highly complex network of cells, signals, and responses that is tightly regulated to ensure that the body can fight off infection without damaging its own tissues.

World Health Organization reports insufficient evidence to support syndromic screening for COVID-19

According to a scientific brief by the World Health Organization (WHO), there is insufficient information to implement syndromic COVID-19 testing for SARS-CoV-2 transmission prevention across land borders.

Virus-only diet can fuel the physiological and population growth of an organism

Over a single day, in the placid waters of a single pond, a million virus particles might enter a single-celled organism known for the minuscule hairs, or cilia, that propel it through those waters.

Novel mRNA-lipid nanoparticle vaccine encoding four mpox virus surface proteins generates robust immune responses against orthopoxviruses

Researchers described a messenger ribonucleic acid (mRNA)-lipid nanoparticle monkeypox vaccine encoding four conserved monkeypox virus surface proteins which induced monkeypox virus-specific immunity and elicited heterologous protection when challenged with lethal vaccinia virus.

Hybrid immunity from mRNA vaccines and breakthrough Omicron infections induces stronger immune responses against Omicron BQ.1.1

Researchers evaluated plasma samples from individuals vaccinated with a fourth booster dose of mono- or bivalent mRNA SARS-CoV-2 vaccine to evaluate the recognition and neutralization capacity against the ancestral (D614G) strain and the Omicron BQ.1.1 subvariant.

23 Dec 2022

Beta-containing COVID-19 booster vaccine found to cross-neutralize variants in non-human primates

A new paper presents preliminary evidence that a new vaccine candidate, designed to boost immunity in already immunized individuals, and containing the adjuvanted Beta spike variant protein antigen, can induce a potent cross-neutralizing antibody response in non-human primate models that is detectable for up to three months.
