Immune disorder (immunosuppression)
In case of an immune disorder, the immune system does not function properly. As a result, the susceptibility to infections is higher. Therefore, additional vaccines may be recommended, but it is possible that some vaccinations may not work as expected. In addition, live vaccines, such as the yellow fever vaccine, may not be administered.
Immune disorders may be congenital or may occur later in life, for example due to an HIV infection, a mild disease or due to the ingestion of immune-reducing drugs. These drugs, such as cortisone, Ledertrexate® and Humira®, are often used in Crohn's disease, rheumatism, cancer, certain skin conditions or after an organ transplant.
Depending on the type of immune disorder, additional preventive measures may be necessary before travelling. In some cases it is not recommended to travel to areas with a high risk of infection or areas without proper medical facilities.
The risk of infection is generally higher in (sub)tropical countries and areas with a lower hygiene standard.
Discuss your travel plans well in advance of departure (eight weeks or longer) with your attending physician and a doctor at a specialised travel clinic.
