Mandatory Flu Vaccine for Healthcare Workers: Not Worthwhile

Area of Science:

• Healthcare Epidemiology
• Infectious Disease Transmission
• Occupational Health

Background:

• The Society for Healthcare Epidemiology recommended mandatory annual influenza vaccination for healthcare workers in 2010.
• This recommendation was made despite a lack of high-level evidence supporting its efficacy.
• Presenteeism among healthcare workers with influenza-like illness is common in healthcare settings.

Purpose of the Study:

• To evaluate the evidence supporting mandatory influenza vaccination for healthcare workers.
• To propose alternative strategies for reducing respiratory virus transmission in healthcare settings.
• To compare the impact of vaccination mandates versus presenteeism reduction.

Main Methods:

• Literature review on evidence for influenza vaccination mandates.
• Comparative analysis of intervention impacts on respiratory virus transmission.
• Modeling the effect of presenteeism reduction on influenza-like illness in hospitals.

Main Results:

• Mandatory vaccination lacks high-level supporting evidence.
• Reducing presenteeism by 2% in a hospital with 70% vaccination compliance equals the impact of a mandate.
• Presenteeism reduction is a viable alternative strategy.

Conclusions:

• Intervention compliance should align with evidence quality.
• Mandates should be reserved for interventions with robust supporting evidence.
• Encouraging vaccination and reducing presenteeism are key to controlling healthcare-associated respiratory virus transmission.
