In 2005, Don Rumsfeld made millions off his holdings in Gilead thanks to a trumped-up bird flu epidemic, for which 60 countries stockpiled Tamiflu. Later studies would show only moderate efficacy for the drug and numerous adverse events, including deaths. https://www.independent.co.uk/news/world/americas/donald-rumsfeld-makes-5m-killing-bird-flu-drug-6106843.html
More recently, Gilead's drug Remdesivir is still the only drug approved to treat Covid despite the fact that it doesn't work. Remdesivir was developed at Ft. Detrick with help from chimeric-virus-psycho Ralph Baric to fight Ebola, which it also doesn't do. https://www.forbes.com/sites/jvchamary/2021/01/31/remdesivir-covid-coronavirus/?sh=52be0de766c2
In Nov 2001, Tony Fauci proposed using Gilead's drug Cidofovir to treat smallpox in case of a bioterror attack or as an additive to to make smallpox vaccines less toxic. This was being proposed as Rumsfeld, formerly Gilead's chairman, was Sec'y of Defense. https://www.govinfo.gov/content/pkg/CHRG-107shrg77048/pdf/CHRG-107shrg77048.pdf
A later study showed that while Cidofovir did make the smallpox vaccine less toxic, but also "significantly compromised vaccine-elicited immune responses and vaccine-induced immunity." https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2612404/
