What prompted this statement?

What prompted this is the slew of new studies and analyses that have recently been aired which have revealed that the mrna ones (and maybe even the JJ????) likely ARE re-writing the genome.

With the mrna vaccines being as novel as COVID itself, there is no way that these people could have known with certainty that the mrna vaccines would work as advertised. There is no way any of them could have known with any certainty whatsoever what the long term effects would be more generally. There are no 5 year, 10 year, or 15 year studies for example. I have problems with the other vaccines that are out there as well, but at least there is decades of data for many of them so we have a realistic handle on what the adverse results would be. There is no way any of them could know these things, and it doesn't take a very smart person to recognize these things, and yet these same stood up and made loud announcements, encouraged social media to censor those who discussed the risks, crushed the careers of doctors who dissented, etc.

I'm only stating that what should be done to them is what they themselves tried to do to these, often with success
.

Do you have links to the new studies? I haven't seen that yet.
