Again, I'm far from an expert, but I've been told that RNA vaccines have been studied for a couple decades now, but the recent vaccines were the first widespread use. But won't a virus deliver several orders of magnitude more RNA to you anyway? Speaking for myself, I've personally known many people including myself who have gotten a variety of vaccines with zero long term consequences, though I did have one friend who gets knocked on his ass for a day or two by them. It's those that chose to forgo the vaccine who have suffered life altering consequences as a result. I actually was talking to a friend yesterday who's thinking about applying for disability since he's tried several times to return to his job as a waiter and been too weak to do the job.

Of course, new technologies will always have the risk of novel effects I suppose. Frankly if I had kids, I'd be more concerned about their constant attachment to phones/tablets and social media like Tiktok or the like. It's hard for me to tell if that's just me getting old and grumpy about technology or if these are in fact new and novel risks, but it's impossible not to notice all the children being carted around with their faces essentially attached to some screen or other.
