Honestly, prior to the covid vaccine I suspect much of this mRNA technology would have been news to more than a majority of physicians. This is fairly esoteric stuff.Well shit, that's all news to me. Everyone I know thinks the use of mRNA is brand new, first use, etc.
AKA, "no one" knows a damn thing about any of this. And that's an obvious health risk to the nation as it fuels anti-vax.
