San Diego HCW Influenza Vaccine RDD Survey – All HCWs  Received Influenza vaccine last year70%  Have never received flu vaccine19.8%  Reasons why not  Not in priority group41.7%  Vaccine side effects16.7%  Vaccine doesn’t work13.2%  I never get sick

Rationale for Mandatory Infuenza Immunization for Healthcare Workers  There is precedent for requiring immunizations for employment in healthcare settings (measles, varicella, hepatitis B)  Multiple studies implicate healthcare workers in the transmission of influenza to patients  Maximum efforts over many years to reach the goal that >90% of HCW be immunized for influenza have failed  People are infectious before they have symptoms so steps to avoid transmission come too late
