Background: Despite the increased infection-related morbidity of patients with chronic kidney disease (CKD), their vaccination coverage is low. Cocooning strategy has not been adequately researched in this group. Our aim was to evaluate vaccination coverage of CKD pediatric and adult patients and their families. Methods: In this prospective, single-center study, we recorded the vaccination coverage of CKD pediatric and adult patients and their families who attend a tertiary University Hospital. Vaccination rates were calculated according to the national vaccination program. Vaccination of pediatric CKD patients was compared to a control group of healthy children. Results: The vaccination rate of 63 hemodialysis patients was low for influenza (61.9%), COVID-19 (79.4% primary, 3.2% booster doses), RSV (50%), herpes zoster (42.4%), hepatitis B (41.3%), <i>Streptococcus pneumoniae</i> (25.4%), tetanus–pertussis (3.2%), and HPV (0%). Their 30 underaged relatives had low vaccination rates for influenza (13.3%), DTaP/Tdap (80%), and Men B (50%), with adequate vaccination for other pathogens. The 53 children with CKD were poorly vaccinated for influenza (20.8%), COVID-19 (0%), <i>Streptococcus pneumoniae</i> (15.4%), Men B (30.2%), DTaP/Tdap (67.9%), MMR (78.8%) and VZV (86.5%), but their vaccination rates for influenza were significantly higher compared to controls. Their 108 adult relatives were inadequately vaccinated for influenza (27.8%), COVID-19 (1.9%), and Tdap (1.9%). Their 35 underaged relatives were poorly vaccinated for influenza (22.9%) and DTaP (80%). Conclusions: Vaccination coverage of CKD patients is suboptimal for vaccines particularly important for their condition and their family members are insufficiently informed about potential contribution to their protection by cocooning strategy.
