ABSTRACTHealth care workers (HCWs) are at great risk of influenza infection and transmission. Vaccination for seasonal influenza is routinely recommended, but this strategy should be reconsidered in a pandemic situation. Between October 2009 and September 2010, a multicenter study was conducted to assess the long-term immunogenicity of the A/H1N1 2009 monovalent influenza vaccine among HCWs compared to non-health care workers (NHCWs). The influence of prior seasonal influenza vaccination was also assessed with respect to the immunogenicity of pandemic H1N1 influenza vaccine. Serum hemagglutinin inhibition titers were determined prevaccination and then at 1, 6, and 10 months after vaccination. Of the 360 enrolled HCW subjects, 289 participated in the study up to 10 months after H1N1 monovalent influenza vaccination, while 60 of 65 NHCW subjects were followed up. Seroprotection rates, seroconversion rates, and geometric mean titer (GMT) ratios fulfilled the European Union's licensure criteria for influenza A/California/7/2009 (H1N1) at 1 month after vaccination in both the HCWs and NHCWs, without any significant difference. At 6 months after vaccination, the seroprotection rate was more significantly lowered among the NHCWs than among the HCWs (P< 0.01). Overall, postvaccination (1, 6, and 10 months after vaccination) GMTs for A/California/7/2009 (H1N1) were significantly lower among the seasonal influenza vaccine recipients than among the nonrecipients (P< 0.05). In conclusion, HCWs should be encouraged to receive an annual influenza vaccination, considering the risk of repeated exposure. However, prior reception of seasonal influenza vaccine showed a negative influence on immunogenicity for the pandemic A/H1N1 2009 influenza vaccine.

Abstract Background Given the nature of their activities, health care workers (hcws) are at higher risk of contracting influenza and transmitting the disease to their patients. Influenza vaccine (IV) remains the most effective way to prevent influenza and its complications. To the best of our knowledge, no national data on IV coverage among hcws is available in Tunisia. The present study aimed to assess the flu vaccination coverage among Tunisian hcws in the 2018-2019 influenza season and factors associated with IV uptake through a study of knowledge and attitudes related to influenza vaccination. Methods A cross sectional study was conducted in Tunisian primary and secondary health care facilities from March to May 2019. Hcws with direct patient contact were recruited according to a self-weighted multistage sampling. Survey data collection was based on a face to face questionnaire containing both open and closed questions. Results A total of 1231 hcws were enrolled in this study. Among respondents, 15.3% (95% CI: [12.3-17.2]) were vaccinated against influenza during the 2018-2019 influenza season. High confidence regarding vaccine efficacy (OR = 3.5, 95%CI: 2.5-4.8), belief that hcws' influenza immunization may decrease illness and deaths among patients (OR = 1.7, 95% CI: 1.2-2.3) and belief that influenza vaccination can reduce work absenteeism (OR = 1.7, 95% CI: 1.2-2.4) were associated with a higher IV uptake among hcws. In addition, participants who mentioned hcws as a target group for influenza vaccination (OR = 2.0, 95% CI: 1.5-2.8) and who were agree that IV is indicated annually for hcws (OR = 3.1, 95% CI: 1.9-4.9) were more likely to receive the IV. Conclusions Influenza vaccination coverage among Tunisian health professionals in 2018-2019 was low. Our findings suggest that knowledge and attitudes regarding influenza vaccine influence vaccine compliance among hcws and should thus be targeted by vaccination campaigns to promote flu vaccine uptake in the health community. Key messages Vaccination coverage among Tunisian healthcare workers was low in the 2018-2019 influenza season. Our findings suggest that knowledge and attitudes regarding influenza vaccine influence vaccine uptake among Tunisian health care workers.
