They changed it because the clotshots were never claimed to grant immunity. Their entire premise behind using mRNA and adenovirus vector to deliver instructions to your cells to produce the spike protein was so that your body would be able to quickly identify a part of the virus, theoretically speeding up recovery and lessening symptoms. I think it's an interesting thing to test but we knew before that that the mechanism for damage from the virus was the spike protein, which is why there were weird symptoms but most people had no problem. Moderate health and your body fought off the virus before you'd be full of the AIDS spike protein.

A lot of people started pointing that out and saying it was a treatment.

So they changed the definition.

But everyone ignored it because they're so addicted to social media their memory only goes back to the last meme or clickbait title they saw.

It's amazing how different the world is when you're not following the social media circle jerk but instead paying attention to what is done. Researching isn't productive if you're not paying attention and using logic, at that point is just seeking validation.
