Do you believe there doesn't need to be long term studies of traditional vaccines? There have been decades of research into them as well.

I believe both mrna and traditional vaccines are safer than covid. I just don't like to take vaccines or medication without longer results than a year. I also agree mRNA vaccines shouldn't have any long term negative effects, but I tend to take the position when in doubt don't take an action.

If in 5 years there hasn't been any widespread negative effects I will probably take it.

I'm not an expert, but my understanding is that the amount of customization in an mRNA vaccine is much less than in more traditional vaccines, so the room for unexpected problems is essentially just the protein.

This is similar to how flu vaccines vary from year to year, but the mechanisms and changes are well understood so the approval process can be streamlined, but we don't expect issues from this year's flu vaccine that we didn't see last year, even though they are different.
