Since my degree is in molecular genetics and minor in technical writing, I feel qualified to explain mRNA in layperson terms. Interested? Our DNA holds all the instructions to make us. They explain how to make skin cells, neurons, blood cells...all the things.

Your complete DNA instructions are in almost every cell in your body, in the nucleus. But we can’t have our blood cells making skin, can we? So we have mRNA (the m stands for messenger). mRNA is a copy of the needed part of your DNA, transported out of the nucleus to be read and

translated into usable “parts.”So we have mRNA already in our bodies all the time. It is highly unstable and doesn’t spread in the air. If it did, we would catch blond hair or leukemia or whatever from ea other, which we know is preposterous. We can’t catch it from one another.

The mRNA is translated by your ribosomes into usable proteins etc. (That may be more than you want to know, but I felt like I dropped you all w/ mRNA instructs for making usable parts).

Think of DNA as an instruction book and mRNA as telegram sent to relay the succinct, important messages.

Basic questions? - Lay em on me. If I don’t know the answers, I know enough scientists to ask- can find out and pass it on.

I explained mRNA but not the vaccine, bec I am not an immunologist. But let me try- The mRNA in the vaccine is an injection of the instructions to make that virus’s coat so our immune cells will take action. The mRNA itself is not a copy from our own DNA& the mRNA does not fight

infection. In effect, it makes it so that Covid19 will no longer be novel to us. Hope that clarifies. Sorry if that created confusion.
