Needlestick injury surveillance during mass vaccination clinics: lessons learned and why more is needed--Tri-County (Denver Metropolitan) region, Colorado, 2009.

Tri-County Health Department studied needlestick injury (NSI) risks in pandemic influenza A (H1N1) mass vaccination clinics through incident reports and an Internet-based vaccinator survey. The mass vaccination clinic NSI rate was 4.9 times the mean rate observed during Tri-County Health Department's 2003 to 2009 routine vaccination clinics. There was also a trend of increased risk for NSI with vaccination inexperience. These findings can be used to improve future mass vaccination clinic safety. Published by Mosby, Inc.
