Oh for heaven's sake, how many times? The mRNA vaccines can’t change your DNA!! Like, it’s not an assumption, it physically can’t!
For mRNA to become DNA you need an enzyme called reverse transcriptase and we, humans, don’t have those (except for in special regions that encode retrotransposons, but that’s a different story and they only work in a specific manner for several sequences)!
To reach the nucleus special signal recognition patterns are also required, as well as special transporter proteins. At last, in order to be inserted into human DNA, you need to get rid of histones that hold DNA together in chromosomes, unravel it (which also requires a set of enzymes and molecular factors), and make cuts in the strand (this also needs to be specifically triggered).
It’s a complex process and even after that, the chances of insertion aren’t that high. Get over it, people! And stop fearing scientists so much, rather fear mass media which spreads so many fakes. That’s where the real horror is…
There are several things missing from your explanation... your explanation, which is right in its simplicity.
1. As you say, the mRNA doesn't do anything other than deliver a message. Here is a good simple explanation
https://www.civilbeat.org/2021/04/what-is-mrna-heres-a-crash-course-on-what-it-does/. But what you don't say is that there are thousands of messages it can be designed to deliver, instructing your cells to do the things that the mRNA can't. So, what are the messages telling the cells to do in the vaxx, and how do you know it?
2. Many people seem to get no adverse effect, or only a minor irritation of some sort, from the mRNA vaxx. Other folks die almost immediately. And there are all kinds of reactions that come about over a period of time, from days to months after the jab, which wouldn't have come about without the jab. See
https://openvaers.com/, a simple, statistical breakdown of the CDCs own info... which is lacking both in quantity and quality. Since adverse effects come about at varying times after the jab, how does anybody know what the longest time for reaction to take place is? It might take 10 years for some people... or longer.
3. There are loads of real doctors and scientists who are not conspiracy people - who often are vaccine proponents - who are expressing dangers in mRNA vaxxes. Do you really think that all these professionals and experts are mistaken? Do you really think that they are simply jealous that a few companies got there before they did?
Inside these 3 points, alone, are loads of sub-points that you blow right by without even addressing them. All your talk about the safety of the mRNA vaccines is pure baloney from example (VAERS) and from the warnings of health professionals all over the place.
Since you suggest by your talk that the vaccines are safe and effective, yet you blow right by the facts, you are either way too ignorant to be talking like you do, or you are a Big Pharma shill, out to help them make money at the expense of the people.
