The FBI concluded with "moderate confidence" that COVID-19 may have been created in a laboratory, based in part on genomic analysis conducted by scientists at the National Center for Medical Intelligence. [98] On 20 March 2023, the COVID-19 Origin Act of 2023 was signed into law. On June 23, 2023, the Biden administration released its report ...
A report by Chinese doctors and scientists published in The Lancet medical journal was titled "Clinical features of patients infected with 2019 novel coronavirus in Wuhan, China".

The details of the study were published in Lancet in November 2020. [14] The Phase 3 SPRINTER trial (SG018), a randomised, double-blind, placebo-controlled study evaluating SNG001 for the treatment of hospitalised COVID-19 patients, was initiated in January 2021. [15] It completed enrolment of 610 patients in November 2021 [16] across 17 countries.
