2020 healthcare workers flu vaccination during covid-19: the experience of Udine University Hospital

Abstract

Abstract Background To prevent flu spread, Italian healthcare workers (HCWs) are annually recommended and given free flu vaccination. This measure of healthcare system protection resulted to be fundamental during COVID-19 pandemic to prevent staff shortage issue. Being the minimum coverage target set at 75%, we decided to evaluate vaccination adherence among HCWs at Udine University hospital. Methods The 2020 vaccination campaign started 4 weeks earlier than usual and was based on a multiple offer strategy including a daily-dedicated clinic, in-ward administrations along with wide vaccination agenda promotion within hospital. The prevalence and the characteristics of vaccinated HCWs were compared with the same 2019 data. Results During 2020, 1868 out of 3839 (48.7%) of HCWs were vaccinated, compared to 29.1% in 2019 (p < 0.0001). Doctors and residents were the most vaccinated categories in both years, being respectively 64.7% and 67.2% in 2020 vs 45.0% and 52.4% in 2019 (p < 0.0001). Midwives showed the best improvement in coverage passing from 44.4% to 20.4% (p = 0.0096). HCWs working in emergency areas and intensive care unit reached the highest adherence in 2020 (61.3%) and the best improvement compared to 2019 as well (37.9%; p < 0.0001). Conclusions Even if the target was not reached, strategies adopted for 2020 vaccination campaign significantly increased HCWs adherence. COVID-19 contribution in this achievement cannot be ruled out, possibly representing a strong reinforcing element for HCWs awareness towards infectious disease prevention. Key messages Despite the improvement in vaccination adherence, HCWs flu vaccination coverage still remains a concerning issue to be addressed. Increased flu shot adherence reached during COVID-19 pandemic should be not only a target to be maintained but even improved next year getting closer to herd immunity.
