Ooh, so you rely on research? Huh, so has any vaccine caused cancer? Or do you think the scientists have ruled that possibility out, just like they've ruled out the possibility of coronaviruses to cause cancer?
We've been looking at coronaviruses for a long, long time. Meanwhile, mRNA vaccines have been deployed for less than 12 months. So I believe our understanding of mRNA vaccines is likely to be substantially less accurate and complete.
There's even info on what the vaccine actually does: https://berthub.eu/articles/posts/reverse-engineering-source...
