Universal vaccination against varicella in Italy: the same opportunity for all children

Varicella is an infectious disease still frequent in Italy, where 8 out 20 Regions have adopted universal vaccination programs starting from 2003. Accordingly to National Vaccination Plan, all Regions should introduce universal varicella vaccination in 2015. An independent multidisciplinary group of experts met to discuss some debated questions. The available evidence of varicella vaccine efficacy in the 8 Regions was evaluated and the evidence of safety of monovalent and combined varicella vaccines are presented. The strategy for introducing universal varicella vaccine in the pediatric immunization schedule is discussed. The expert group concludes that available evidence supports the active offer of varicella vaccine in all Italian Regions and that catch up programs for susceptible cohorts should be encouraged
