The mRNA molecules used in the Moderna (mod) and the Pfizer-BioNTech (p-tech) vaccines contain genetic information for the Spike protein of the SARS-CoV-2 viral component
A protein that emerges from the enveloped virus's surface in the form of a large structure known as a spike or peplomer is referred to as a spike protein or peplomer protein.
Moderna and Pfizer vaccines are based on mRNA and contain genetic information for spike protein. This allows the body to develop immunity to spike protein and defend itself against viral infection.
The Spike protein of SARS-CoV-2 binds to the receptor on the host cell and causes virus-cell membrane fusion, which is essential for the virus's invasion.
