Here's my guess – The jab is (at least partially) a big compliance test. It's easy to pretend you believe in whatever politically correct BS passes for "moral" in order to get along with people, but to willfully take an injection that could kill you is much more of a commitment, a sign that you either trust the authorities with your life, or are willing to risk it when enough pressure is applied, I.E social pressure, risk of losing your job, etc.

Plenty of people died as a result, and this was inevitable – The goal wasn’t to make something that would kill/maim every single person who took it, but it needed to be dangerous enough to make any person with even the slightest discernment think twice about it. The real purpose was that it divided the entire country into “compliant” and “non-compliant”, with the former having a registered system to prove their status. And given the frothing-at-the-mouth dehumanization campaign of the latter group, I suspect there are very dark plans yet to be implemented.
