The “Comirnaty” vaccine prepares the body to be resistant to COVID-19 disease.
The vaccine contains genetic information (mRNA) on the spike protein, coated with fine particles of fat that prevent the breakdown of mRNA.
When a person is given the vaccine, the cells in his body are able to "read" the genetic information encoded in the vaccine and begin to produce the spike protein. The human immune system recognizes this protein as alien to the body and activates T cells, stimulating the production of antibodies, which are part of the natural protection against foreign substances.
Later, if the vaccinated person's body is introduced to the SARS-CoV-2 virus, his immune system is able to recognize the virus and is ready to fight it: antibodies and T cells, acting together, can terminate the virus, prevent its entry into the cells of the body and destroy infected cells, thereby helping protect yourself from COVID-19 disease.
