Z26.9: Need for immunization against unspecified infectious disease

You have received one or several vaccinations.

You can be vaccinated against various pathogens. Vaccination is intended to help the immune system become familiar with a pathogen. After the vaccination, the immune system produces certain substances to fight the pathogens. If you come into contact with the pathogens later, the immune system can then take action against them more quickly. The pathogens are then no longer able to harm the body as much, if at all. Vaccines are used to vaccinate. Vaccines can be injected into a muscle or under the skin. There are also vaccines that are swallowed. Vaccines can contain weakened or dead pathogens. It is also possible to only use parts of a pathogen. There are also vaccines that contain a small piece of the blueprint of a pathogen. The body’s cells themselves then form small fragments of the pathogen for a short time and show them to the immune cells. Some vaccinations have to be repeated several times in your life so that you are protected from the relevant pathogens over an extended period. Pathogens and viruses are examples of a pathogen. If nearly everyone in a community is vaccinated against a disease, this disease will no longer be able to spread so well.

You have received a vaccination against certain pathogens.
