>>127418721.:All life is based on DNA. DNA translates to mRNA, mRNA is translated to proteins.
2.:The virus has spike proteins, these hold on to a cell, so it can inject viral RNA into your cell (fucknig it up, useing it to make more viruses)
3.: your immune cells recognise the virus based on spike protein, but if you have never encountered the virus, your immune cells wont recognise it.
4.: we inject mRNA coding the spike protein. (this is the vaccine). Your cells make some of the spike protein. Your immune cells learn how to target spike protein.
5.:you catch the virus, but your immune cell know what spike proteins look like, and have a standing army ready to fuck them up.
Now you wont die if you catch the rona.
TL:DR get vaccine, get beer, get laid.
