>>12701868its derived from the virus, it literally cant be any worse than the virus. Its really not magic, one persons ribosomes aren't going to be radically different than anothers...
If they were lol life would be really hard, food and nutritional requirements would be radically different for everyone, not everybody would be biologically compatible. It would just fuck everything up, viruses and bacteria would be way more powerful and potent. This is the hypothetical world you're living in.
But in the real world, things are a lot more consistent because we're all the same species and almost all identically the same on a cellular level. There is no chance that the vaccine can do anything worse than give them an allergic reaction, that they would have got anyways from the virus should they ever come into contact with it. (not to be confused with allergic reactions from the vax carriers themselves, this isn't a problem unique to mrna vacs)
Do you ever think about if the people who bolted on the suspension of your car made any mistakes? Or if the plane mechanics made any mistakes on the tune up before your flight? Or if the builders of your home made any mistakes when they built the roof and floors? If they had made any mistakes in the vac, it would have never gotten through trials.
