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.

Underlying genetic cause for MIS-C complications after COVID-19 identified

A recent Science journal study determined the underlying cause of MIS-C related to SARS-CoV-2 in some children. It hypothesized that monogenic inborn errors of immunity (IEI) is the primary reason for this condition. Identifying these inborn errors is expected to help elucidate the disease's cellular, molecular, and immunological basis.

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.

Scientists find key reason for ongoing loss of smell in long-COVID

In a recent study published in the journal Science Translational Medicine, researchers reported that long-term anosmia following coronavirus disease 2019 (COVID-19) could be a result of persistent T-cell mediated inflammation occurring in the olfactory epithelium even after the elimination of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) from the olfactory tissue.
