Barriers for vaccination of healthcare workers

Outbreaks of vaccine preventable diseases (VPDs) in hospital settings remain a challenge even in countries with established (childhood-) vaccination programs. Healthcare workers (HCWs) with an updated vaccination card play an important role in reducing the risk of nosocomial spread of VPDs. Yet, in many places, HCWs report their immunization status to be unknown or not updated. In times of a global pandemic, the debate on vaccination of HCWs is as hot as ever; do HCWs have an increased responsibility to get vaccinated against VPDs? If so, how do we increase vaccination uptake rates among HCWs? Mandatory vaccination against VPDs for HCWs has been introduced in some countries, but it may cause ethical dilemmas and not be culturally acceptable everywhere. We looked at vaccination policies and HCWs' attitudes toward immunization against VPDs. We found that missing vaccine policies and lack of knowledge of VPDs, vaccination benefits, as well as inadequate organization around HCWs' immunizations were important barriers to have a complete vaccination record. A systematic approach to employees providing information of VPDs and vaccinations, going through their vaccination cards and offering antibody testing where appropriate or a shot of a missing vaccine could support staff to adhere to vaccination schemes.
