Relevance of the study is determined by the increasing number of vaccine-preventable
infections and the need to monitor vaccination coverage among children.
The aim of the study was to assess the coverage and timeliness of preventive vaccinations,
including tuberculosis vaccination, among children born in 2024 and registered at the
outpatient clinic.
Materials and Methods: A retrospective cross-sectional analysis of 204 child development
records (form No.112) was conducted manually, after which the data were reverified using
electronic immunization records in the Registry, corresponding to form No.63.
Results and Discussion. The results showed that 173 children (84,8%) received the
tuberculosis vaccine, and 180 children (88,2%) received the hepatitis B vaccine, 113 children
(55,4%) received the first dose of Infanrix-Hexa, 85 children (42%) received the second dose,
and Pentaxim was administered to 85 children (42%). Immunization with Prevenar: first dose
— 116 children (57%), second dose — 81 children (40%), third dose — 34 children (17%). The
measles, rubella, and mumps (MMR) vaccine was given to 61 children (30%). OPV revaccination
was performed in 23 children (11%).
Conclusion: 84,8% children received the tuberculosis vaccine and 88,2% received the hepatitis
B vaccine. The insufficient coverage and delayed timing of vaccination against pneumococcal
infection (third dose), measles, rubella, mumps, and poliomyelitis (fourth dose, revaccination)
are associated with children not having reached the recommended vaccination age, the
presence of medical contraindications, refusals, and unidentified reasons.
Keywords: vaccination, coverage, the tuberculosis, vaccine BCG, children, immunization
