Why fatigue from long COVID goes beyond simply feeling tired

In a recent study posted to the medRxiv* preprint server, researchers in the Netherlands examined the role of inflammatory genes, cytotoxic T-lymphocytes (CD8+ T cells), and pro-inflammatory cytokines in long-lasting severe fatigue experienced by a large number of coronavirus disease 2019 (COVID-19) patients.

Vaccination-induced responses for Omicron subvariant neutralization

Researchers summarized existing data on SARS-CoV-2 Omicron variant’s sub-variant (BA.1, BA.1.1, BA.2, BA.2.12.1, BA.3, and BA.4/5) neutralization. They also performed a comparative assessment of cross-neutralizing responses of Omicron subvariants in comparison to the Wuhan-Hu-1 strain (prototype) antigen.
