What immunocompromising conditions are an indication for a 3-dose HPV schedule?

ACIP recommends vaccination with 3 doses of HPV vaccine for people age 9 through 26 years with primary or secondary immunocompromising conditions that might reduce cell-mediated or humoral immunity. Examples include B lymphocyte antibody deficiency, T lymphocyte complete or partial defects, HIV infection, malignant neoplasm, transplantation, autoimmune disease, or immunosuppressive therapy. In these circumstances, the 3-dose series is recommended even for those who initiate vaccination at age 9 through 14 years when the routine recommendation is for a 2-dose series.
