MRNA-based vaccines have had lots of injuries (some were taken off the market for causing blood clots, which was also lumped into 'misinformation campaigns' for a long time).
It's impact has been hidden and many people have lost their jobs by even questioning it. If this weren't the case, misinformation against these kinds of vaccines wouldn't have flourished. Not to mention the fact that you can't even sue the vaccine companies for any harm it causes you.
The vaccines didn't do much to help stop the spread. Herd immunity did.
