BackgroundThe growing phenomenon of vaccine hesitancy and the severe economic crisis may have affected compliance with the National Immunization Program (NIP) in Greece over the last years. We investigated compliance with the NIP among children attending nurseries in the urban area of Thessaloniki.MethodsA cross-sectional study was conducted, including nursery attendees born between 01/01/2014-01/10/2015 in each of the municipalities of Thessaloniki urban area. Public and private nurseries were randomly selected. Immunization data were anonymously collected from the child's health booklet. Both coverage and timeliness of immunization were recorded for all recommended vaccines according to the NIP.ResultsIn total, 432 children with a mean age of 2.9 years were studied, of which 245 (57 %) were attending private nurseries. Full coverage was >90 % for most of the recommended vaccines except for pneumococcal (81 %), meningococcal serogroup C (68.3 % and 82 % for 2011 and 2015 schedule, respectively), hepatitis A (38.9 %) and rotavirus (25.9%) vaccine. Delay rates for one or more doses ranged between 21-90.3 % for all vaccines; time of median delay ranged between 3.8-6.7 months. Lower coverage and higher delay rates were observed for Roma children.ConclusionsWhile high coverage appears to be sustained for most of the recommended vaccines, delay of scheduled shots may compromise age-appropriate protection. Suboptimal immunization against pneumococcal, meningococcal serogroup C, hepatitis A, and rotavirus infections may increase morbidity in this age group and needs to be addressed.
