Mass dog vaccination is the cornerstone of eliminating canine rabies, a disease responsible for nearly 59,000 human deaths annually. Yet many regions struggle to achieve the sustained vaccination coverage required, often because dog owners do not participate fully in campaigns. Researchers from Tanzania investigated whether engaging communities directly could address these barriers and improve vaccination outcomes.
The team, led by C. Duamor, F. Lankester, and K. Kreppel, implemented engagement activities across two wards, including village meetings, training on safe dog handling, video screenings, posters, and leaflets. In one ward, community leaders were also involved in planning and implementing a real vaccination event to evaluate feasibility.
Data from household surveys, focus groups, and observations revealed significant improvements in understanding dog behavior, dog handling, and safe interaction. Knowledge gains were strongly associated with age, dog ownership, previous training, and prior dog-bite experience. Conversely, fear of dogs was linked to lower knowledge levels. Importantly, knowledge significantly increased after engagement activities, confirming the effectiveness of educational outreach.
The study also uncovered social and emotional factors that influence participation. Many respondents cited weak bonding with their dogs as a barrier to restraining them during vaccination. Despite this, a remarkable 92% believed vaccination has no negative effects on dogs, indicating strong support for the practice. When asked to take part in vaccination implementation, communities successfully fulfilled most roles, although lack of motivation for volunteer tasks remained a challenge.
The findings underscore that community-engaged approaches—especially those that build understanding of dog behavior and empower people with practical handling skills—may be essential to sustaining high vaccination coverage in regions where rabies remains endemic.
