This is untrue, researchers have been testing various mRNA therapies on people for 30 years, with it being first done in vitro in 1990 then in vivo in 1992 [1]. Lipid nano particles were first used around the same time.
> the vaccine was rushed faster to public access than any other vaccine before
This is only true if you ignore the development of the mRNA vaccine platform for flu, rabies, and zika that predated the pandemic by years. The novel development here was swapping in new protein encoding. If you look at this as a continuation of that process, then it's only a little faster than normal, and a lot of that was due to the FDA switching sequential steps in the process to be parallel.
> We have absolutely no idea if there are any long term side effects of these vaccines.
This isn't a meaningful claim for 2 key reasons. There has never been a vaccine that had serious side effects that did show up shortly after vaccination[2]. The history of mRNA treatments began as an experiment in gene therapy, but has largely ben abandoned because the effects never lasted long enough. As of 2020 this is an ongoing area of research[3]. No one has figure out how to stabilize mRNA so that it has long lasting effects.
> Both candidates Biden and Harris
They're both craven, ignorant politicians, who cares what they said when the other guy was in power.

[edit] All that said, I am no pro mandate but seriously you should all voluntarily go get vaccinated IMHO.
