NIH runs an intramural program as well as funding extramural research. While most of their money goes to extramural grants, they have a huge intramural program in suburban Maryland. The main campus employs over 20K, and at least 4 NIH scientists have gotten the Nobel prize.You are drifting into taboo territory. The "institutions" do NOT want to confront what you see.
We busted the global warming mess the same way. They presented simulations models as if they were factual solid data. We busted them before Climate gate "leaks" where the tricks were exposed.
NIH, CDC, WHO don't exactly do the lab work. They hold the purses and funnel money to partner labs which do "research, modeling, etc. and push papers" The ugly problem is peer review where most papers can't be or have not been replicated. They just got "endorsed".
If a partner lab publishes findings which do not validate experimenter's bias, they may not see more funding.
No peer reviewer is expected to replicate the results of the paper they are reviewing. That would be a colossal waste of time and money and would only rarely produce new data.
