U11.9: Need for immunization against COVID-19, unspecified

When someone is infected by this coronavirus it may trigger the Covid-19 disease. The aim of the vaccination is to prevent Covid-19.

2 different types of vaccines are used for the vaccinations. The vector vaccines are one type. They contain viruses that pose no risk to humans. A small piece of the coronavirus blueprint has been packed into these harmless viruses. The mRNA vaccines are the other type. In the case of mRNA vaccines, a small piece of the coronavirus blueprint has been packed into a tiny particle of lipid. Once the vaccines are injected into the muscle the small piece of the coronavirus blueprint is transported to the body’s cells.

The small piece of the coronavirus blueprint stimulates the body’s cells to produce the same pieces of coronavirus for a short time. In contrast to a real infection, however, these are not complete coronaviruses, but rather small fragments of the virus surface. The small piece of the coronavirus blueprint is then broken down and it does not remain in the body’s cells. The immune system now recognizes a part of the virus surface and it produces certain substances that can combat the coronaviruses. If someone comes into contact with coronaviruses later on, the immune system can act against them more rapidly. So the coronaviruses are then unable to damage the body as badly.
