title: [Antiviral immunization of immunocompromised adults, literature review].
abstract: OBJECTIVE
  Immunization, by preventing infections, has a major interest for the immunocompromised subjects. The aim of this article is to make a point on data concerning efficacy (in terms of immunogenicity) and safety of viral vaccines available in France and to synthesize existing guidelines for four groups of patients: solid organ and hematopoietic stem cell transplant recipients, HIV infected persons and patients treated by immunosuppressive drugs for a systemic disease.
  
  
  BACKGROUND
  Available data about vaccines immunogenicity and safety for immunocompromised adults are rare. However, those data indicate that, when immunization contraindications and recommendations are applied, vaccines remain well tolerated and most of the time immunogenic, even if the percentage of responders is lower compared to non immunocompromised persons. Still, the specific guidelines that have been elaborated for immunization of immunocompromised adults are imprecise and incomplete, emphasizing a lack of data about this topic.
  
  
  CONCLUSIONS
  Clinical studies remain necessary to precise vaccines immunogenicity and safety for immunocompromised adults. In the meantime, a harmonization of immunization practices for immunocompromised adults should be proposed, so as to help practitioners to succeed a better immunization coverage for these patients.
