The importance of immunization in cancer prevention, treatment, and survivorship
Immunosuppressive cancer treatments can increase the risk and severity of a range of potentially vaccine-preventable infections.
Among children and young adults being treated for certain cancers, immunosuppressive therapies can erase immunity previously acquired through vaccination, dramatically increasing the risk of vaccine-preventable infections. The authors assert that vaccination during and after immunosuppressive treatment is necessary to rebuild immunity and protect the most at-risk children.
Children with cancer often rely on herd immunity as protection from vaccine-preventable diseases, so vaccinating family members and health workers is critical. Herd effects may be the only source of protection against diseases in which the vaccines are not recommended for immunosuppressed children, such as the measles vaccine.
