Those were not failures. They accomplished everything they intended to accomplish.
=> Created a new and infectious Pathogen.
=> Tested distribution mechanisms.
=> coordinated with media entities to produce PANIC, worldwide.
=>Tested the population's tolerance of, and in some cases, demand for totalitarianism and found it fertile ground, indeed.
=>Tested use of social media and news platforms for their ability to censor posts from any source in order to protect and promote the approved narrative.
=> tested ability to marginalize longstanding and revered professionals in their fields of expertise and silence anything they might say contrary to the narrative.
=> Tested the ability of scientists around the world to construct studies that would produce desired results, enabling the governments of the world to be taken for billions of dollars without any liability for results.
=>Tested the ability to demonize medications in common use, to restrict availability of those medications in favor of using untried approaches, medically, and promote those aspects of the narrative widely using media of all sorts, while suppressing and censoring voices to the contrary.
=> made a lot of money for products that did not prevent, limit the transmission of, or cure disease, with no liability whatsoever for adverse impacts of those treatments.
About the only thing they failed to do was stop the pandemic.
