I don't think those numbers mean what you think they mean. It's not just 95% vs 99.5% chance of dying.
The major worries for younger people now are not dying from COVID it's catching it and having long term issues like vasculitis, myocarditis, lung problems, or whatever the hell else will pop up. If the vaccines are truly that effective, getting it would make the chances of getting COVID on top of getting a severe case would be essentially zero.
Yes maybe there could be some vaccine complications but most complications show up shortly (few months) after a vaccine injection. By the time us normal people get it, millions of people will have received theirs and we will have 6 months to a year of follow up data. I think I will take the miniscule chance of a vaccine issue vs the known COVID chances of hamstringing myself for the rest of my life not to mention hurting anyone in my family or community.
