Introduction. The relatively stable incidence of most controlled infections shifts the focus of public attention from the need for vaccination to the likelihood of post-vaccination complications.
 Aim. To examine the adherence of various population groups and health workers to vaccine prophylaxis and analyze the reasons for anti-vaccination scepticism.
 Materials and methods. A survey was conducted on the attitudes towards vaccination among one thousand nine hundred thirty nine respondents including 485 doctors of various specialties (163 pediatricians, 86 surgeons, 85 obstetricians-gynecologists, 76 neurologists, 75 neonatologists), 117 nurses, 295 parents, 1042 students. The significance of differences was assessed using Student’s t-test.
 Results. An insufficient level of adherence to vaccine prophylaxis has been established: 43.1% of parents vaccinate their children selectively, 35.4% according to the national calendar, 17.1% refuse categorically, and 4.4% have a medical refusal. The main reason for refusal is fear of complications (30%). Less than half receive information from health workers (45.6%), the main source being the media (49.1%). Among health workers, adherence to vaccine prophylaxis is highest among pediatricians (86.1%), significantly lower among neurologists (35.6%), surgeons (43.7%), obstetricians-gynecologists (62.6%), nurses (79.5%). The main reason for distrust of vaccination is fear of post-vaccination complications, narrow specialists more often choose the answer “better to get sick”. Among medical university students there is a significantly higher adherence among senior students in paediatrics (63.6%) compared to students in undergraduate (40.8%) and medical school (48.8%). However, 5% of those surveyed do not plan to vaccinate their children in the future. Polytechnic students have a more negative attitude towards vaccination accounted for only 36.4% vaccinated according to the National Calendar and 30% do not plan to vaccinate their children in the future.
 Conclusion. There is a clear need for additional training programs on vaccination to raise the awareness of health care workers on this issue, which will provide a strong rationale for the importance of immunization to patients and their parents.
