Experts like Jian-Rong He note that these findings do warrant immediate changes to clinical practice. Instead, they highlight the importance of:
: The study found no significant association between maternal infections and other types of childhood cancer, such as brain tumors or lymphoma, suggesting the risk is specific to leukemia. Context and Perspective Experts like Jian-Rong He note that these findings
: Utilizing existing prevention strategies, such as influenza vaccinations, to reduce the overall burden of prenatal infection. Current scientific theories, such as the "delayed infection"
