Abstract Introduction: Vaccination of healthcare professionals is important not only for their own protection but also for protection of their patients. Furthermore, vaccination coverage of general practitioners has been linked with the vaccination coverage of their patients. Therefore, studying the vaccination coverage of general practitioners, as well as their reasons for no vaccination, is important. Methods: A cross-sectional study with questionnaires was conducted between December 2018 and January 2019, targeting all general practitioners (GPs) in the island of Crete. The questionnaires were conducted through telephone interviews for GPs of the private sector, while for public-sector GPs most questionnaires were distributed by collaborators. We examined the complete vaccination coverage for the following vaccines: influenza, measles, hepatitis B and pertussis (Tdap). We also examined the association between vaccination coverage and the following factors: gender, age, sector (private vs public), geographical area and method of questionnaire delivery (distribution of questionnaires vs telephone interviews). Finally, we examined the reasons of vaccine hesitancy for influenza as well as the correlation between influenza vaccination and vaccination coverage for the other 3 vaccines. Εμβολιασμοί και Πρόληψη Λοιμώξεων σε Παιδιά και Εφήβους Ιατρική Σχολή – Πανεπιστήμιο Κρήτης 9 Results: Response rates were high (260 of 294 GPs) in all geographical areas, both in the public and private sector. Vaccination coverage was below target for all examined vaccines; 56% for influenza, 25.9% for measles (2 doses), 68% for hepatitis B (3 doses) and 17.8% for pertussis (Tdap). Vaccination coverage for influenza was higher in older age groups (p<0.05), while coverage for the other 3 vaccines was higher in younger GPs (p<0.05 only for measles). Female gender was associated with higher rates of complete vaccination for measles (p=0.02) and hepatitis B (p=0.04). No significant differences were noted comparing private to public sector GPs. Vaccination coverage for influenza and Tdap was significant higher in Rethymno compared to the other 3 cities of Crete. Misconceptions were found among GPs regarding vaccinations for measles, influenza and Tdap. The most common reasons for non-vaccination for influenza were: negligence (47%), lack of necessity (low risk 29.6%, preference for natural immunity 4.3%), fear of side effects (7.8%) and doubtful vaccine efficacy (4.3%). Conclusions: Vaccination coverage of GPs in Crete remains low. This study revealed significant misconceptions among GPs regarding vaccination for measles, pertussis and influenza, that should be the focus of future informative interventions. Considering that negligence was reported as the most common reason for non-vaccination, organized interventions for on-site vaccination of GPs may significantly increase vaccination rates in Crete.
