Study of tolerance and effectiveness of a varicella vaccine in leukemic children.

Chickenpox could be a severe disease in immunocompromised patients. Live attenuated vaccine is now available. We conducted a trial in 37 leukemic children with OKA varicella vaccine. Full immunization was observed in all 20 seronegative patients. Few side effects and no generalized vaccinal infection were observed. Further studies are warranted to assess the benefit of vaccination in leukemic patients considering the effectiveness of Varicella Zoster Immuno-Globulins and Aciclovir.
