Vaccinations in children during and after oncological treatment and in selected hematological diseases: Recommendations of the polish society of pediatric oncology and hematology

Abstract

Infections are one of the biggest threats for patients during and after treatment of neoplastic diseases. For children with non-oncological hematologic conditions, infections are associated with an increased risk of complications and may be a trigger to the occurrence or exacerbation of the health problem. Vaccinations are the only effective and safe way to prevent infections. Recommendations regarding their implementation change over time, depending on the current epidemiological situation, access to vaccines, as well as data on the safety of their use in risk groups. The paper presents current recommendations of the Polish Society of Haematology and Pediatric Oncology regarding the principles of immunization of children with cancer and hematological diseases.
