Failure to become immunized when caring for patients: an ethical and professional obligation.

In late September 2012, changes to the Rules and Regulations Pertaining to Immunization, Testing, and Health Screening for Health Care Workers (R23-17-HCW) were proposed to reflect the most current (2011) recommendations of the Center for Disease Control’s (CDC) Advisory Committee on Immunization Practices (ACIP). One of the proposed changes drew many people to a public hearing: the requirement that all Health Care Workers (HCW) either receive seasonal influenza vaccine or wear a mask when providing face-to-face patient care during “period(s) in which flu is widespread.” A brief review of the rationale for mandating seasonal influenza vaccination among HCWs follows, along with ethical implications. The risks and benefits of seasonal influenza vaccination are reviewed as well.
