There's no long term data. Period. That may not worry you, and that's fine, but others may look at that differently and come to different conclusions for themselves.
That's not true. There is long term data. Your argument is equivalent to saying that because the antigen in the flu shot changes every year, we have no idea what next year's flu shot will do. I am telling you that there is quite a bit of data that indicates there will be no long term effects. Choosing to ignore that data does not make you right. There is rarely 100% certainty about anything in life.
The fact is, that there is an incredibly low probability of long term effects. No one can say it's 0%, nor is it 0% for simply walking out your door in the morning.
