The issue is not the effect on sperm, because as both you and I have pointed out, the paper says the effect subsides.
The issue is that when being advised (or browbeaten) to get this shot, you probably weren't informed beforehand that for the next 3 months your swimmers might not be in tip top shape. This might not matter to you or me, but maybe it would to couples that are trying to concieve, for instance.
It's not just that people weren't warned, it's that we were presented with a bunch of a priori reasoning about why mRNA shots couldn't possibly have this effect. So it raises the question, which of the other assertions (which were not backed by long term clinical data, because none existed) were also wrong?

Does that make sense?
