I have a new theory about the lockdowns, their real purpose

Once covid first started spreading, maybe they realized this was a novel coronovirus they could weaponize using vaccines causing antibody dependent enhancement. BUT if too many people already had immunity to the virus in the first and second wave then the vaccinated wave may be not as strong. For instance if someone recovered fully from covid before they got vaccinated, maybe the body already has encoded the antibodies for protection, and ADE is rendered useless in subsequent vaccinations. I keep hearing people that "did everything right" and wore masks, got vaccinated, yet They are the ones who got the worst cases and died after their bodies were primed with the vaccines. If we are going under the assumption that people who really took covid seriously were less likely to have caught it, then the virus is still novel to their bodies. That paired with 250 times viral loads from vaccinated people can cause severe outcomes to occur.

TLDR: The lockdowns real purpose was to keep the virus novel, then using the vaccines to prime the body for severe outcome when it is inevitably exposed.
