The last time I checked, when you go through a process of attempts and failures (aka trial and error) in order to find success... That process is specifically called "experimentation". Which makes the Vax an experiment. Which makes the mandates insane. This is essentially a public admission of the fact that the vaccine is an experiment and you are the guinea pigs. https://thelibertydaily.com/pfizers-global-president-of-vaccines-in-2016-vaccines-take-years-and-many-failures-before-we-succeed/
