Do we have data on 5, 10 years after usage? I'm fairly certain that there won't be anything either (based on what experts have said), but we should withhold making assertions without data to back it up, right?
I've tried. I have not found any hard data from sources I would trust. I've found lots of opinions penned by people I have no reason to trust.
Anyone who doubts the safety of this new immune system programming is obviously either a science denier or a paid [insert foreign country] shill.
Most vaccines take 10-15 years to develop, so that should probably be my target, but I'm willing to take on some extra risk.
