T88.1: Other complications following immunization, not elsewhere classified

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.

After a vaccination, many people experience mild discomfort. The injection site may be red or swollen. There may also be some pain. There are particular problems in your case. For example, you may have a skin rash.
