Unless there’s a last-minute meeting of the minds, it looks like any extension of the World Trade Organization’s (WTO) five-year intellectual property waiver for COVID-19 vaccines will be shelved, at least for now.
The biological processes giving rise to the central nervous system symptoms of long COVID remain a mystery. But multiple studies suggest they do not appear to be a result of a direct viral infection of brain tissue. The latest such research, which appeared online in Nature Neuroscience on Feb. 16, 2024, demonstrated that local immune response in brain tissues persisted long after SARS-CoV-2 virus had disappeared.

Trawsfynydd Therapeutics Inc. has received approval to initiate a first-in-man phase I trial of the novel best-in-class COVID-19 treatment, TRX-01, an inhibitor targeting the SARS-CoV-2 viral main protease (3CL, Mpro).
COVID-19 severity remains open to several questions. Researchers at the University of California Los Angeles (UCLA) have revealed how SARS-CoV-2 causes acute inflammation instead of the symptoms of a common cold. This effect could be initiated by the peptide fragments of the coronavirus released when the host eliminates the virus, which can form pro-inflammatory complexes that trigger an amplified immune response.
