UNLABELLED: Healthcare associated influenza is a serious public health problem that contributes to patient morbidity and mortality.

OBJECTIVE: To determine the seasonal influenza vaccination rate and reasons for its acceptance among healthcare workers in a hospital located at the metropolitan area of Puerto Rico.

METHODS: Self-administered, anonymous questionnaires were distributed to 120 volunteer healthcare workers and ancillary staff.

RESULTS: Immunization rates for the 2009 Influenza A (H1N1), seasonal vaccines 2009 and 2010 seasonal influenza vaccine were 50%, 53% and 65%, respectively. Determinant factors for acceptance of vaccination in 2010 included obtaining the 2009 vaccines, not knowing someone with adverse effect to the vaccine, and believing the vaccine should be mandatory for all healthcare workers.

CONCLUSION: Influenza immunization rate is below the recommended rate to decrease healthcare associated influenza infection. Our results serve to confirm that education is needed to improve immunization rates among these healthcare workers and eliminate misconceptions about the vaccine.
