If anyone wants to learn more and have a computer technical/programmer background rather than biology, this article reversing the pfizer mRNA code was very interesting:
https://berthub.eu/articles/posts/reverse-engineering-source-code-of-the-biontech-pfizer-vaccine/I'm not vaccinated yet, but still willing to take vaccine when it becomes available. After reading about different vaccines a lot I would prefer Sputnik V, because my focus is not political, it's technical, and I rather pick one with better base protection than one with milder symptoms once infected with Covid.
Thank you for pointing me to this, it's been a fascinating hour reading this stuff. Finally STEM (Science Translational Medicine journal) is not only cited, but has excellent information that I can somewhat read :-)
Will probably spend the rest of the weekend reading this stuff. I remember hearing about the Tau replacement for U, the fact that they used it like this is a great example of how some discoveries that seem kind of pointless years ago turn out to be very handy later....
