An old question that I’m still hearing is if it’s true that the vaccines can't affect your DNA. This is entirely true – mRNA vaccines cannot alter your DNA. (1/8)
The best way to think of mRNA is as instructions for our body. Our body produces mRNA all the time - this is how our body provides instructions to cells on how to produce many different proteins normally. (2/8)
In this case, rather than our body making mRNA, the vaccine provides it, but it gets read and managed the same way as always. (3/8)
Once the instructions (mRNA) are inside the muscle cells of the injection site, the cells use them to make the spike protein piece which looks just like the spike protein on the virus. (4/8)
After the protein piece is made, the cell breaks down the instructions and gets rid of them. (5/8)
Next, that cell displays the spike protein on its surface. Our immune systems recognize that the protein doesn’t belong there and begins building an immune response to it. At the end of this process, our bodies have learned how to protect against future infection. (6/8)
The role of mRNA in this process was instructions for our bodies. mRNA is not DNA. mRNA never even enters the nucleus of the cell, which is where our DNA is kept. (7/8)
Soon after it is finished using the instructions, our cells break them down and get rid of the mRNA. This means there is no way that the #COVID19vaccines will alter our DNA. #ProtectMB (8/8)
