Vaccination coverage and susceptibility against vaccine-preventable diseases of healthcare students in Athens, Greece.

BACKGROUND: Vaccination of healthcare students is important to protect them from acquiring and transmitting vaccine-preventable diseases (VPDs) to high-risk patients and other healthcare workers (HCWs). The aim of the current study was to estimate the vaccination coverage, the susceptibility against VPDs, the knowledge and attitudes toward vaccinations of healthcare students studying at the Athens Technological Educational Institute. METHODS: The study was conducted during the academic year 2012-2013 using a standardized questionnaire. RESULTS: The mean knowledge score (correct answers) of healthcare students about the vaccines that are recommended by the Greek Ministry of Health for HCWs was 41%. Completed vaccination rates range from 19.6% for varicella to 80.2% for tetanus-diphtheria. A history of measles, mumps, rubella, varicella, hepatitis A, hepatitis B, or pertussis was reported by 8.2%, 4%, 5.4%, 70.4%, 1.5%, 0%, and 3% of students, respectively. Susceptibility rates were 20.5% against measles, 26.4% against mumps, 13.9% against rubella, 15.7% against varicella, 47.8% against hepatitis A, 17.3% against hepatitis B, and 19.8% against tetanus-diphtheria. Mandatory vaccination of HCWs was supported by 145 (96.7%) students. CONCLUSIONS: There are significant immunity gaps against all VPDs among healthcare students in Athens. A system to easily identify non-immune students should be established in association with efficient reminder systems. Education of healthcare students about VPDs and vaccines will improve their attitudes toward vaccinations and their vaccination coverage. Mandatory vaccinations should be considered for HCWs in order to promote safety within healthcare facilities.

Influenza vaccination acceptance among health-care workers: a nationwide survey.

We conducted a nationwide survey to investigate reasons for influenza vaccine uptake or refusal among health-care workers (HCWs) in Greece. Vaccination rates increased with increasing age, and among HCWs working in Northern Greece, in direct contact with patients, and with influenza vaccination in the past. Self-protection was the main reason for vaccination (89.1%), whereas 55.2% of HCWs reported vaccination to protect patients. Main reasons for refusing vaccination were perception of not being at risk for influenza (43.2%) and fear of vaccine adverse effects (33.4%).

Strategies to increase influenza vaccine uptake among health care workers in Greece.

The aim of the current study was to investigate the contribution of various strategies to increase influenza vaccine uptake among health care workers (HCWs) working in hospitals in Greece during the 2005-2006 season. A total of 132 Greek public hospitals participated in the study. The mean HCWs vaccination rate against influenza during 2005-2006 was 16.36% compared with 1.72% during the previous season. Logistic regression analysis showed that the implementation of the following strategies was significantly associated with influenza vaccination rates above the mean vaccination rate: a mobile vaccination team (OR 2.942, 95% CI 1.154-5.382, p-value 0.016) and lectures on influenza and influenza vaccine (OR 2.386, 95% CI 0.999-5.704, p-value 0.036). In conclusion, in Greece influenza vaccination rates among HCWs remain low; however, the implementation of specific strategies was associated with increased vaccine uptakes.
