The vaccines are a MacGuffin. (Or a Red Herring; guess it depends on how the movie ends.)

They are not important in themselves.

The entire point of the "virus" and its subsequent "vaccine" is to create fear of death so great that people will willingly give up their right to bodily autonomy, all on the promise that the government will protect them. (From something the government created just to scare them into obeisance.)

Plot twist one: There was no virus. There was aerosolized spike protein; aka airborne AIDS. Getting that stuck in your respiratory tract mimicked a virus.

Also, it lowered your immune system so you would indeed pick up any other virus that happened to be hanging around. So you'd probably test positive for a corona/SARS virus.

Plot twist two: There is no vaccine. There is only experimental gene therapy, designed to act as an agent for

1. sterilization;

2. euthanasia; and

3. the groundwork for a "cattle branding" system allowing for a) total surveillance and b) control of our thoughts and actions.

Regarding the branding, that mark (!) uses luciferase to glow under UV light.

And it inserts a barcode or serial number.

There are videos of people showing how their veins glow and of someone using a device over the shot area that then displayed a serial number.

And yes, they appear to have used HIV fragments in at least some of these shots. The Australian government stopped developing its own mRNA shot because people were testing positive for HIV.

But what about the others?
