FTR, FDA has approved a product (not a mRNA vaccine) using lipid nanoparticles in 2018.

mRNA vaccines had also (limited) human testing before these trials in the past years (mostly Phase 1).

I know. I don't see how it refutes what I said. I'm not anti-vaccine, I was just replying to the parent comment suggesting that because these mRNA vaccines don't use adjuvants they wouldn't have side effects.

All medicines represent calculated risks -- risks that are often worth taking, but still risks.
