Humoral and cellular response to primary and booster COVID-19 vaccination in immunosuppressed patients

Researchers posted the results of a retrospective observational cohort study in which they determined the humoral and cellular responses in ISP to primary and booster doses of COVID-19 vaccines.

SARS-CoV-2 Omicron variant's infectivity, vaccine breakthrough, and antibody resistance

A recent study uses an artificial intelligence model to investigate Omicron's mutations and its infectivity, vaccine escape capability, and susceptibility to monoclonal antibodies.

SARS-CoV-2 omicron variant predicted to cause fewer deaths in Florida

Scientists have predicted a lower number of infections and deaths caused by the omicron variant of severe acute respiratory syndrome coronavirus 2 in Florida

SARS-CoV-2 shown to spread through cell-to-cell transmission

A new study investigated SARS-CoV-2 cell-to-cell transmission in the context of cell-free infection and compared it to SARS-CoV.

Declining effectiveness of the BNT162b2 vaccine in adolescents infected with COVID-19

Researchers have conducted a retrospective matched case-control study to determine the protection period conferred by the BNT162b2 vaccine on adolescents aged 12 to 16.

SARS-CoV-2 spike engagement of ACE2 shown to prime S2′ site cleavage and fusion initiation

In a new study, researchers used a cell-cell fusion assay to extract potentially cleaved spike protein products from syncytia in order to explore the functional and biochemical characteristics of spike (S) protein when it engages its receptor ACE2 in living cells.

Association of vaccination status with Long COVID symptoms

Scientists examined whether vaccination was associated with reporting long-term symptoms post-SARS-CoV-2 infection.

Researchers plan to review the effect of SARS-CoV-2 on male reproductive health

In a protocol published in BMJ Open, researchers from the Chengdu University of Traditional Chinese Medicine plan to review current studies in this area.

SARS-CoV-2 Delta sublineage AY.4.2 shows no increase in cell entry or antibody evasion

Researchers from Germany, in their recent study published in the journal Cellular & Molecular Immunology, have evaluated the mutations in the S protein of one such SARS-CoV-2 strain, a Delta sublineage AY.4.2, which is currently expanding in the UK, and have found that it neither contains any potential for increased cell entry nor antibody escape.

New lab-on-a-chip platform for detecting SARS-CoV-2 in resource-limited settings

A recent study shows how a novel and integrated lab-on-a-chip platform can represent a rapid, affordable, and exact molecular diagnostic tool for detecting severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The paper is currently available for free on the medRxiv* preprint server while it undergoes peer review.

History of SARS-CoV-2 infection affects longitudinal responses to BNT162b2 vaccine

In a recently published article in the journal Cell Reports, scientists have demonstrated that individuals with or without a history of coronavirus disease 2019 (COVID-19) exhibit differential humoral and cellular immune responses 14 days after receiving mRNA-based COVID-19 vaccine developed by Pfizer/BioNTech. However, at a later time point, the responses become comparable between the two groups.

Influenza vaccination does not affect risk of SARS-CoV-2 infection or COVID-19

A new study published in The Journal of Infectious Diseases examined if influenza vaccination altered the risk of SARS-CoV-2 infection and clinical outcomes of COVID-19. The study included health care workers (HCWs) from Denmark who were offered influenza vaccination.

Engineered small extracellular vesicles for the neutralization of SARS-CoV-2

Characterizing these engineered sEVs, the researchers demonstrated that the soluble angiotensin-converting enzyme 2 (sACE-2) loaded sEV successfully binds and thus inhibits the entry of wild-type SARS-CoV-2 as well as its variants, protecting against SARS-CoV-2 infection. They also demonstrated the therapeutic efficacy of these engineered sEVs in vivo.
