A "shot" could be anything, from a bullet, to a basketball, to some other drug. Gotta have an adjective or two there to know exactly which "shot" I'm talking about.
DNA death shot's not bad, but maybe a little overboard. Spike spreader shot, how's that?
The J&J and Astrazeneca ones use DNA (and then produces the mRNA). I remember the flame wars of people arguing that J&J was "better" because it didn't use mRNA (no, it is actually more invasive by actually inserting new DNA into the cell that then codes the mRNA to then code the spike protein).
The article posted the other week by the supposedly beloved Dr. Peter McCullough, however, blew that out the water as he used data that had only considered those who had taken the Chinese vaccine, which used neither DNA nor mRNA technology and instead uses dead or weakened virus. So it would be the mere presence of the spike protein that is causing the symptoms, and that would mean those who got viral infections also had that.
Some use the expression "Jim Jones jab".
