Objective: To increase influenza vaccination rates of HCWs by adopting a mandatory vaccination/declination policy
Methods: During this year's influenza vaccination campaign, a mandatory vaccination/declination policy was implemented with an established deadline for compliance.
Results: Between 2004 and 2009, employee influenza vaccination rates improved from 63% to 90.5% with the introduction of a mandatory vaccination/declination policy. For the current season 98.8% of HCWs complied with the policy. 402/5622 employees (7.2%) declined vaccine overall, 9.5% were not immunized. Underimmunized (<85%) HCWs by unit included those in transport, radiology, sedation, cardiac surgery, and pain management.
Conclusions: HCW influenza vaccine coverage has improved over six seasons with a dedicated occupational health and infection control staff. Highest coverage was seen this season with the adoption of a mandatory vaccination/declination policy. Mandatory influenza vaccine policies without declinations must be considered to further increase influenza vaccination rates.
