'''Immunosuppression''' is when the immune system is unable to protect the body from disease. This condition can be caused by disease (like [[HIV]] infection or [[cancer]]) or by certain drugs (like those used in [[chemotherapy]]). Individuals whose immune systems are compromised should not receive live, attenuated [[vaccines]].<ref>http://www.cdc.gov/vaccines/about/terms/glossary.htm#i</ref>
