False. Studied doesn't mean it worked or was feasible. This is the first mRNA vaccine approved for use in humans. The lipid nanoparticles used to deliver the mRNA was first tested in humans in 2015 but wasn't an approved drug.

Appeal to solipsism is not a compelling argument. It’s obviously been studied quite a while and feasible, the results speak for themselves. That govt is slow to react until forced is not apropos of anything.
