"Researchers created 200+ novel "barcoded" SARS-CoV-2 viruses in the lab using reverse genetics, funded by NIH grants (R01AI169022, U01AI151810). These constructs do not exist in nature and were engineered for tracking in transmission studies.""All constructs were modified with the D614G spike mutation, known to enhance transmissibility and viral replication — a hallmark of gain-of-function research. This raises alarms given the lab-leak theory surrounding COVID-19’s origins." FULL STORY at above link.
