Why Coverage of Influenza Vaccine Is Not Enough in Patients Receiving Chemotherapy?

Instead of strict recommendations of experts of doing vaccination in chemotherapy patients, they may not be aware of its necessity, except to be encouraged by their responsible healthcare workers. as it is clear that morbidity and mortal- ity of influenza is high in immunocompromised patients.1,2 according to some reports, mortality rate of influenza infection can reach 9% among oncology patients.3 vaccination against influen- za is recommended in immunosuppressed pa- tients, including those receive anticancer chemo-therapy.4 absence of immunization commands, particularly against influenza, endangers the quality of life in patients with cancer.3 general- ly, although patients with cancer respond posi- tively to vaccination, the utility of influenza vaccination is very low in this population.
