It's a big bundle of confusion that's too difficult to explain with so few words, but we can give it a try.
Both sides of the debate were bombarded with propaganda. Neither was wrong, but largely for reasons they didn't understand. The vaccines targets certain genetics, so the ones shouting about it being a death wish weren't wrong, they were just wrong about how widespread it would be. On the other hand, the ones saying it wasn't that bad were also right; a lot of saline was injected and way more people than we told didn't get it.
For the most part, the vaccine probably won't do much and if it does, there's a good chance it's reversible or only would do very much to people that are on the brink anyways.
This is the best I can explain it so far.
