mRNA vaccine mechanism

Viruses have spike proteins that are produced with the help of messenger RNA (mRNA). This mRNA is then coated in lipid that works as mRNA vaccine. This is then administered into a body, where it activates immune system. This activation of immune system then produces antibodies and activates T-cells. Now the body has developed immunity against virus. Whenever the virus enters the body, the immune system, including T-cells and antibodies recognize spike proteins and destroy the virus.
