The vaccines being used now aren't for Covid. They're for the next virus. The next virus will be the real virus that kills tens of millions if not more.
The government will continue to push the vaccines until a few months before the midterm elections. At this point most of the unvaccinated will be people who refuse the jab because they oppose the current political party in power. The kill virus is released and the unvaccinated die. Civilization freaks out and anarchy rules the streets until order can be restored.
The government then goes before the people and says "The vaccines we told you to take have saved your lives. We have restored law and order. We have proven we have your best interests at heart and that you can trust us." The survivors who have just gone through hell are so grateful to still be alive that they now gladly view the government as their savior and protector.
So in the end the government has -
- Reduced the population
- Eliminated most of it's political opposition
- Created a reason to cancel the midterm elections
- Created a population which trusts the government and will do as they're told without question
Sounds like government's wet dream if you ask me.
