Studies on effectiveness of palivizumab in children with hemodynamically significant congenital heart disease (HS-CHD)
(13) Chang and Chen, 2010, USA [32]Hospital record review 2000–2006 Children aged <2 years with HS-CHDPrepalivizumab era (2000–2003) versus postpalivizumab era (2004–2006) 266 children with HS-CHD19% reduction,
HS-CHD patients comprised of 0.56% of all RSV hospitalization in prepalivizumab era and 0.46% in palivizumab era
Requires further investigation of cost-effectiveness of palivizumab in children with HS-CHDLow

Studies on effectiveness of palivizumab in children with cystic fibrosis (CF)
(14) Winterstein et. al., 2013, USA [40]Cohort study1999–2006Children < 2 years with CFNo palivizumab versus palivizumab Nonprophylaxed group: 575
Prophylaxed group: 2300
Nonprophylaxed group = 4.1 (2.8–6.0)/1000 season months
Prophylaxed group = 2.4 (0.8–6.6)/1000 season months

Studies on effectiveness of palivizumab in children with Down syndrome (DS)
