It fulfills the definition of a vax; the “emergency” means they get to short-cut testing and safety.
It really is made just from (not “with”) dead COVID virus particles.
It doesn’t tell your body to make spike proteins, either via DNA or mRNA injected into your system.
Your body gets a shot of this, and it says, hey, I don’t recognize you. Imma make antibodies to you.
Just like it would for being exposed to live Sars CoV2. Except this virus doesn’t break into your cells and start replicating. Cause it’s dead as a door nail.
