Non-deliberate immunosuppression can occur in, for example, [[ataxia–telangiectasia]], [[complement deficiency|complement deficiencies]], many types of [[cancer]], and certain chronic infections such as [[HIV/AIDS|human immunodeficiency virus]] (HIV). The unwanted effect in non-deliberate immunosuppression is [[immunodeficiency]] that results in increased susceptibility to [[pathogen]]s, such as bacteria and viruses.<ref name=2nih/>

Immunodeficiency is also a potential adverse effect of many [[immunosuppressant drug]]s, in this sense, the scope of the term ''immunosuppression'' in general includes both beneficial and potential adverse effects of decreasing the function of the immune system.<ref>{{Cite journal|last1=Lallana|first1=Enrico C|last2=Fadul|first2=Camilo E|date=2011|title=Toxicities of Immunosuppressive Treatment of Autoimmune Neurologic Diseases|journal=Current Neuropharmacology|volume=9|issue=3|pages=468–477|doi=10.2174/157015911796557939|issn=1570-159X|pmc=3151601|pmid=22379461}}</ref>

[[B cell]] deficiency and [[T cell]] deficiency are immune impairment that individuals are born with or are acquired, which in turn can lead to immunodeficiency problems.<ref>{{Cite web|url=https://patient.info/doctor/immunodeficiency-primary-and-secondary|title=Immunodeficiency (Primary and Secondary).
