Knowledge and attitudes of healthcare personnel about vaccination of migrant and refugee children and adolescents.

Background: The number of migrants to Greece has increased considerably the last decade. This study assessed the knowledge and attitudes of healthcare personnel (HCP) toward vaccination of newly-arrived children and adolescents in the Aegean islands, a major port of entry of migrants and refugees to Europe. Methods: The study was conducted from September 2020 to January 2021. All (166) HCP employed in the public health sector of the Aegean islands were invited to participate. A structured questionnaire was used to collect demographic data and data about their knowledge and attitudes toward vaccinations for migrant and refugees. Results: A total of 120 HCP participated (72 % response rate), including 54 (45 %) physicians, 43 nurses (35.8 %), and 23 health visitors (19.2 %). Sixty-seven (55.8 %) HCP were aware of the national vaccination guidelines. Health visitors had higher rates of knowledge about the national vaccination guidelines, compared with nurses and physicians (87% versus 44,2% and 51,9%; p-value-0.001). Overall, 73 (60.8 %) HCP were aware of vaccinations during the first examination upon arrival. Primary-healthcare physicians were more likely to be aware about the time of vaccine administration compared with hospital-based physicians (74 % versus 50 %; p-value = 0.006). Out of 120 HCP, 45 % knew that vaccination guidelines apply to all newly-arrived migrant and refugees and 65 % that vaccinations are free-of-charge. Overall, 67.5 % of participants supported no serology testing before vaccination, 21.8 % were against free-of-charge vaccinations, and 55 % recommended only priority vaccinations. Conclusions: There is a need to increase HCP' awareness and knowledge through training programs and tailored protocols focusing on vaccinations for newly-arrived migrant and refugee children and adolescents in order to promote effective vaccination of this vulnerable population.
