The RNA is the actual instruction set that creates

The RNA is the actual instruction set that creates proteins.. the theory behind both of these vaccines is if you take that instruction set, and have animal cells make the proteins on the outside of the virus, the immune system will recognize the virus when it comes across it.

You can't alter someone's DNA code with RNA for virus spikes.. DNA is the reference; it stays in the library and only carbon copies / RNA leave the building, effectively. The RNA from these vaccines should never make it to the DNA to even interfere.

The biggest issues with mRNA vaccines is their manufacture and storage.. Pfizer has already had some slip-ups in that department. What happens in that event is the mRNA gets fragmented, and instead of putting out a full virus protein, it's just chopped up junk, which won't help anyone's immune system recognize the virus.

Eventually the cell breaks down the mRNA and the cells stop making the viral protein.

Anyone saying masks don't work are quacks and / or morons. Viral load has been shown over and over to have a direct effect on severity of disease. Masks, used properly, reduce exposure. The US has had over a year to produce masks that would actually have great protective capabilities but everyone's still walking around with cloth on their face, for the most part.

Vitamin D has shown to be important, moreso for people with higher melanin and in higher latitudes. Postentially moreso for women that men, as well. It won't save you if your genetics and Covid are destined for a tragic encounter.
