Early vaccination protects against childhood leukemia: A systematic review and meta-analysis.

ABSTRACT: Leukemia is the most commonly diagnosed childhood cancer, although its etiology is still largely unknown. Growing evidence supports a role for infection in the etiology of acute lymphocytic leukemia (ALL), and the involvement of the immune system suggests that vaccination may also play a role.
