Elimination of dog-transmitted human rabies worldwide will require large-scale dog vaccination campaigns. However, this places participating vaccinators at increased risk. Data from the 2016–2017 Haitian mass rabies vaccination campaign was analyzed to determine dog bite incidence among vaccinators. A survey was then developed for completion by all identifiable bitten vaccinators covering demographics; experience and training; bite episode details; attitudes toward dogs and rabies; and medical care. A parallel group of unbitten vaccinators was also surveyed. Dog bite incidence was 0.03% (43/127,000) of all dogs vaccinated. The capture, vaccinate, and release method of vaccination carried a significantly higher risk of dog bite (0.35%, 6/1,739 vaccinations) than other methods (P < 0.001). Twenty-seven bitten vaccinators, and 54 control vaccinators were included in the survey analysis. No differences were found between groups in demographics, experience, or training. However, bitten vaccinators were significantly more likely than the control group to have experienced a dog bite before the study period (P < 0.001). This may be associated with a lesser appreciation of dogs, and/or a poorer ability to interpret dog behavioral signals within this group. Although 98% of the control group indicated they would seek medical care for a dog bite, only 35% of bitten vaccinators sought such care. On a yearly basis, for the Haitian campaign, a full series of postexposure rabies vaccinations for all bite victims would prove more cost-effective than preexposure vaccination of all vaccinators. These findings may prove useful for the planning and safety of future mass dog vaccination campaigns.
