Z20-Z29: Persons with potential health hazards related to communicable diseases
Z28: Immunization not carried out
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.
There can be various reasons why a vaccination was not carried out. For example, the person may have opted against the vaccination. Or the person may not tolerate certain ingredients in the vaccination. Moreover, some vaccinations cannot be given if the person has certain illnesses or is pregnant.
