Implementation of a pertussis immunization program in a teaching hospital: an argument for federally mandated pertussis vaccination of health care workers.

BACKGROUND: As pertussis disease becomes more common, health care-associated outbreaks have been reported with increasing frequency. Often, these clusters are costly and labor intensive to investigate and contain. It is clear that health care workers are among the adults who transmit pertussis to susceptible infants. Recent focus on patient safety, together with a concern for protecting employees in the workplace and those they expose elsewhere, has spurred interest in optimizing measures to prevent infection and disease transmission. Shortly after a tetanus toxoid, reduced diphtheria toxoid and acellular pertussis vaccine adsorbed booster was licensed and became available, we designed, launched, and analyzed a campaign to immunize the employees of our institution against pertussis.
METHODS: To optimize acceptance of a tetanus toxoid, reduced diphtheria toxoid and acellular pertussis vaccine adsorbed booster by employees, we adopted a program consisting of a 3-phase publicity and educational model and a 3-phase vaccine delivery approach.
RESULTS: Despite extraordinary resources dedicated to this program, and our institution's better than average annual uptake of influenza vaccine, less than one third of our eligible employees were immunized. A significant number of employees declined to be vaccinated for inappropriate reasons.
CONCLUSION: A campaign of this kind is quite labor intensive and expensive, yet limited overall vaccine uptake was achieved. A federal mandate to require pertussis immunization of all health care workers appears to be a more effective way to protect our patients, employees, families, and society.
