A quarter of centers did not have an on\u2010site protocol for the immunizations. At the time of transplantation, pediatric candidates were fully immunized (80%\u2013100%) in 57% and 33% of the SOT and HSCT programs. Variations in the time between vaccine administration and admission to the waiting list were reported between the centers, with 2\u2009weeks for inactivated vaccines and variable time (2\u20134\u2009weeks) for live\u2010attenuated vaccines (LAVs). Almost all sites recommended immunization in the post\u2010transplant period, with a time window of 4\u20138\u2009months for the inactivated vaccines and 16\u201324\u2009months for MMR and Varicella vaccines. Only five sites administer LAVs after transplantation, with seroconversion evaluated in 80% of cases.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The immunization coverage of European pediatric transplant recipients is still inconsistent and far from adequate.
