There isn't much point in replying to trolls like @whatwhaaaaat who claim the COVID-19 mRNA vaccines "don't even work". It's just willful ignorance at this point.
I know, but per your second point, arguing the semantics against willful ignorance doesn't work.
I simply opt to point out that there was and is an old-school vaccine because the focus on the mRNA side of things baffles me.
