Worksite influenza immunization programs. Insight into the implementation and cost-benefit.

The most important factors in cost-benefit analyses of worksite influenza immunization programs are vaccine cost and administration, vaccine efficacy, and the assumptions used to calculate lost productivity from worker absenteeism or decreased effectiveness. Based on several models published in the literature, estimates of savings per healthy working adult employee could be anticipated to range between dollars 15 and dollars 50. Variations of this net savings are primarily based on assumptions of productivity estimates of the employee. Efficient large worksite influenza immunization programs are feasible and worthy of employer consideration for economic and employee satisfaction reasons.
