Once attached, the spike undergoes a dramatic transformation, stretching before partially turning inside out to forcefully fuse with our cells. WebSep 1, 2024 · The spike protein is found on the surface of the virus that causes COVID-19. COVID-19 mRNA vaccines are given in the upper arm muscle. Once the instructions (mRNA) are inside the muscle cells, the cells use them to make the protein piece. After the protein piece is made, the cell breaks down the instructions and gets rid of them. open a commodity account
