No, it hasn't. Biden, Biden's wife, the presidents of every major country now have come down with Covid repeatedly, showing that NOTHING, nothing at all works like they propagandized: not the worthless so-called vaccines, not the masks. Not the lockdowns. Not the stupid 6-foot distancing. Nothing worked. It was all lies, lies, lies.
You leftist people!! You are so easily fooled, and you never figure it out. At least we on the right DID most of us figure out what a scam this has been. You all are still spouting the hopeless, obviously wrong lies they told you simply to try to train you to be controlled, just like the Chinese do.
The fact is they simply couldn't fix Covid. They wanted to "fix" it, but they couldn't. I've studied epidemiology for years as an amateur and I know it always, forever, takes literally decades to find a vaccine that works and doesn't kill people itself, like polio did at first. Well, OF COURSE they couldn't do it in a few months! But instead of admitting that, they lied and lied and lied and lied and lied. And ruined the economy and a lot of lives. All to train us to be sheep and obey government orders no matter how stupid and useless they were.
