Is it true that SARS-CoV-2 was engineered as a bioweapon?
Partly. Self-published preprints and dossiers assert SARS-CoV-2 was engineered as a bioweapon, but they offer assertion rather than verified evidence. Peer-reviewed reviews and the Proximal Origins analysis state the virus shows no signs of purposeful manipulation and that the bioweapon theory has been dismissed by most experts.
